If the engine "Troit" and does not work one of the cylinders, then hearsely distinguishable "bu-boo bu" - the engine sounds not as usual. We will understand most of the reasons and how to correct the situation with your own hands.

What consequences

When the motor "Troit" and shakes - it begins to quickly wear out. Because of this, compression is reduced, conditions are created to create loops on cylinders and pistons. The motor begins to work in another temperature mode, starts overheating. It sometimes turns out that everything is checked, and the engine is still "Troit".

Therefore, on points we will try to disassemble the procedure for diagnosing under normal conditions, when there are no special devices to look inside and accurately determine the cause.

Blame spark plugs

To begin with, fill the candle from the cylinder and carefully examine it. What will you see? If the engine works correctly, the color of the side electrode and the insulator will be light and slightly brown. Such a candle should work. If we see the NAAR black - this is the reason for which the engine can work unevenly. It is enriching fuel or dropping oil.

Causes of Nagara:

• long work at idle and in warm-up mode;
• reduced compression in the motor;
• violation of the phases of gas distribution;
• incorrect operation of the injector (nozzles are clogged with mud);
• incorrect operation of the oxygen sensor.

Because of Nagara, the ignition candle can not fully work or irregularly, because it interferes with the normal flow of sparking. I will transfer a look at the case. It should be white and it should not be vertical black stripes or points. The presence of this says that the candle makes his way and will not work normally.

If the visual inspection satisfied, then check the spark when scrolling the starter. We insert the candle into the tip of the high-voltage wire, put on the motor weight and scrolling the motor starter look - accesses the spark between the candle electrodes or not. If there is a good spark of saturated space between the candle and the mass of blue color - Everything is fine.

If the spark does not slip or slips, but barely noticeable - this is the main reason why the engine began to tackle. Verdict - replacement of candles to new ones.

Inspection of high-voltage wires

If everything is in order with candles, then carefully consider each high-voltage wire separately. Some machines are installed individual ignition coils - it means that we skip this item. First, we will examine the tip of the wire inserted into the candle. It should be a monophonic color and not have a plaque on the inner surface and points outside.

If there is data causes, the high-voltage wire has been working in extreme mode (defective candle of the machine, an enlarged gap), which served as a malfunction. The result is to replace the wires to new ones. If you do not pay attention to the change in the color inside the tip of the high-voltage wire in time - then the wire will trigger.

To determine the state of "high-voltakers", we measure resistance using a digital multimeter. Values \u200b\u200bare different on concrete Enginebut should not exceed 20 com. If one of the wires showed the resistance value is significantly less than all the others, it means it is faulty and the cause of interruptions in operation lies.

It happens that confused high voltage wires. It happens because there are numbers on the ignition coils that indicate the number of the cylinder to which it works. But not all know this or they are poorly read because of dirt. On machines, the number of cylinders are written on the ignition distributor, it is only necessary to clean the lid from dirt and immediately will be visible.

Fault Injectors and Injector

The motor can trim due to an injector or nozzle malfunction in cases:

• Malfunctions of the injector itself (found rarely);
• Due to the use of low-quality fuel, applications "Purifiers fuel system»;
• Turning out or closer supply chains or controls to the injector.

Other reasons

One of the reasons why the engine "Troit" is a bad compound "Mass" with a car body. There was a case when the mass was moved from vibrations and the motor worked with interruptions, because There was no reliable contact. After pulling the connections, the engine earned normally. There may be a floating mistake when the mass of the mass is moving on bad roads. It turns out that you started the car, and the mass was moving along the way. When all the ways are trimming - and it does not hurt it.

Video - What is worth checking?

If one of the sensors does not work - an error will appear that the auto scanner can be considered. If it is not - it means the reason in the mechanical part. If you failed to find a malfunction, you should use computer diagnostic. As a rule, many cases of non-worn motor operation can detect only a special device. Otherwise, throw out the "extra" money to replace good details.

One of the common malfunctions of the motor - interruptions in the work of one or more of its cylinders, which in the motorist environment they say "Troit Engine". Everyone who came across this phenomenon is probably familiar with his symptoms. But what are the causes and consequences of such a breakdown, not all car enthusiasts know. Today we will tell you in detail why the engine troit, how to diagnose and repair the motor.

The reasons for which the engine "Troit"

Trojite the engine can constantly or from time to time. General signs of engine troops are as follows: on idling of motor compartment Strong uneven vibrations begin to penetrate into the salon, the sound of the working motor is changed (it "rods", moves with high "notes" to low, and back). The unit begins to consume more fuel, and its power drops, and from exhaust pipe Incompute sounds are distributed, accompanied by a thick smoke of white or black. If at least one of these signs is present - it means that the "heart" of your car has a problem with one or more cylinders. If they are not eliminated on time, then the consequences can be very deplorable - up to power aggregate.

We characterize the most common reasons why the engine troit is four:

• later or early ignition of the fuel and air mixture (TVS);
• uneven fuel in the motor cylinder;
• disadvantage or excess air in the cylinder combustion chamber;
• falling a compression level.

Consider them in more detail.

Cause №1. If the fuel mixture is flammable in the cylinder before or later due to the term, then the spark plugs are to blame, which produce too weak spark, or the formation of sparks occurs in a non-time. Weak sparking occurs due to the fact that there are harmful sediments on the candle housing and its electrodes (Nagar), which interfere with the breakdown of sparks.

Another reason weak spark is the destruction of its insulator. In the place where the insulator collapsed, a nagar stain is formed, which prevents the formation of a normal spark. If the sparks are not completely, there may be several reasons: worn cap Candles, failed high-voltage wire (congestives current K), breakage of ignition coils or switch. The last phenomenon is quite rare, but check the state of the switch, which is in charge of the ignition distribution, will not be superfluous.

Reason # 2.. The uneven fuel ingress into the cylinder when a smaller amount is poured into the combustion chamber, often due to the malfunction of the fuel pump parts (the discharge part or a reduction valve) or pressure valve in the fuel supply system. If the cylinder gets more than necessary, the amount of fuel, the problem is probably lies in fuel injectors - They contaminated or failed. Finally, another "fuel" reason for the engine troops - failure in work electronic block Control (ECU) by a power unit that may erroneously increase or decrease the supply of gasoline / diesel in the cylinder.

Cause No. 3.. Surplus air in the cylinder is a sign of depressurization of the air supply system in which the air filter includes the inlet hose, throttle nozzle and receiver. The disadvantage of this important component of the fuel-air mixture in the cylinder can be triggered by a contaminated air filter or a breakdown of throttle valves.

Failure in the operation of the mass flow of air or position sensor throttle valveECU perceives like a motor requirement to add or drop the amount of air into the combustion chamber, can also be caused by the motor trimming.

Cause No. 4.. Low or full of its absence is perhaps the most serious reason why engine Troit. This is the first sign that a piston or valve or a valve, or piston rings completely worn out in a non-working cylinder. It is not necessary to do without serious repair of the power unit.

In addition to the common reasons for which the engine Troit, there are secondary. They are said when the motor troit periodically - "on the cold" (when) or "on the hot" (with medium or high revolutions). Here the most common malfunction is valve: when, when idling, their gap increases, the engine trimming is manifested, which, as it is heated, it passes (the gap is restored). Conversely, the gap increases when the engine reaches operating temperatures - then its troit "on the hot" with all the signs described above.

Methods of diagnosis

If all the signs of the fact that the engine troit is evident, it is necessary to carry out its diagnosis and determine which cylinder has failed and for what reason. Check can be carried out independently, but you can drive the machine to the service station, where its power unit is subjected to detailed computer diagnostics. In most cases, it is possible to determine the cause of the motor's troops itself, but if the cylinder refused to work, for example, due to low compression, it is better to seek help to an experienced motorist.

Step 1. Determine the problem cylinder. Testing the cylinder work on the engine center, so you need to comply with all security measures. We turn on the ignition, open the hood, listen to the operation of the motor. I remember with what sound it works. We begin to disconnect high-voltage wires to the ignition candles.

When the working cylinder is turned off, the motor begins to trim with double power. When the ignition candle is disconnected on the non-working cylinder, the motor behavior will not change. Another method - the high-voltage wires do not touch, and alternately turn off the chips that control the fuel supply from the nozzles to the cylinders. When one of the chips is disconnected, the engine operation will not change - so we will detect the closing cylinder.

Step 2. Check the condition of the high-voltage wire and spark plug. Disconnect the high-voltage wire and carefully examine it. If you notice damage to the insulating layer - it means that the cause of the malfunction is in the wire. Also, it will be useful to check the integrity of the conductive conductors - if it is broken or burned out, then there is a breakdown or internal resistance (we measure the multimeter, we carry out with normal readings), which interferes with normal current supply to the candle. But if the wire is intact, then the problem is in the ignition candle. We must unscrew it and carefully examine.

If you find visible damage to the candlecloth or its electrodes (Nagar), it will have to be replaced. If the candle is a mustache, we are looking for a problem on which the engine is troit further.

Step 3. We measure whether the air enters the cylinder. The lack of air enriches the fuel assembly, which leads to the troop of the motor. We check the tightness of the air supply system: overlapping the inlet tube, compressor by vacuum hose We supply air to a cylinder under a pressure of 0.5-0.7 atm., Listen to. If the characteristic hiss is heard, it means that the air supply system is depressurized. Another diagnostic method - check air filter. If he is clogged, the air in the cylinder goes little. We put the diagnosis and the mass supply sensor - for this you will need a laptop that connect to the diagnostic connector.

Step 4.. We define how much fuel is in the cylinder. To do this, measure the pressure in the fuel system with a pressure gauge (up to 7 atm.), Which we attach to the nozzles ramp. It is necessary to measure pressure in 4 stages: When the ignition is turned on, at idle, on the working turns with a fuel pressure with a fuel regulator and with a reversed valve tube. If it is low, then the elements of the fuel pump or pressure valve in the fuel supply system have fallen. If normal - check the state of nozzles, they can be contaminated or in general fail. Finally, check the operation of the fuel system on diagnostic equipment - Erogors in the ECU are possible.

Step 5. We measure compression in the cylinder using a compressometer that insert the problem cylinder into the hole, we turn the ignition and increase the engine speed. Remove the testimony several times. If the compression fell by 15%, the cylinder wear the piston, valve or piston rings. To determine the specified breakdown, you will have to disassemble the engine.

How to make the engine not Troil

After conducting diagnostics and determining, for what reason the engine troit, proceed to correcting the situation. Well, if the problem is only in candles or high-voltage wires - they can be. The same - about ignition coils and switch. But if the reason for clogging the fuel or air system is necessary to tinker. Contaminated nozzles need to be rinsed with a special means (for example, injection System Purge), if necessary, change the oxygen sensor (), since it will probably work incorrectly.

dirty and clean nozzles

If the flushing of the result did not give (the fuel continues to pour the candle), then we change them to new ones. The same applies to the fuel pump and other elements of the fuel system, which fail when the motor trimming is better to replace them than to repair and put in place. Replacing the air filter and elements of the air supply system that are depressurized - also needed during repair. Well, the final chord is the correction of the ECU errors, which lead to engine troop.

The main causes of trimming

The moment of ignition is incorrectly installed.
- Air seats occurs in the system of vacuum reinforcement brakes.
- Ignition Candles Malfunction. It is worth noting that this problem It is most common, since the spark plugs need to be changed after passing through the car every 20,000 kilometers (this indicator depends on the recommendations that each car gives constructors).
- Test of high-voltage wire, which is suitable for a spark plug.
- malfunction of the installed condenser.
- Violation of the system's tightness in the intake manifold area.
- The appearance of a slot of one of the piston, the valve.
- breakdown piston ringsTheir deformation and wear also lead to the emergence of this problem.
- Incorrect adjustment of valves of gas distribution.
- Great degree of wear of rocker.
- breakfast installed gasket GBC.
- Any type of wear (hardening, breakdown, destruction) oil-challenged caps.
- With incorrect adjustment of the carburetor, there may also be a violation of the cylinders.
- The state of the installed timbrel shaft, the bearing of the rotary plate.
- Air filter clogging.
- The loss of tightness of the membrane of the vacuum regulator of the ignition advance.
- The use of unsuitable candles (not only dimensions, but also other parameters of this element) to this engine are taken into account.

Engine Troit

Engine Troy - the definition under which should be understood to failure in the work of the engine, when one or more cylinders do not work partially or completely. If you say otherwise, the process of combustion of the fuel and air mixture in individual cylinders is disturbed, which causes unstable work Motor at idle, under load and in transition modes.

The engine testing is manifested in the form of reinforced vibrations of the power unit, the engine significantly loses its power. Ignition gauges may be observed, which are accompanied by strong cotton in the exhaust system. The motor can trim both occasionally and constantly, only at idle or under load, on a cold, hot, etc. Next, we intend to answer the question of what engine troops are, as well as consider the main reasons why the motor begins to trim.

Why motor starts troiting

Engine Troy is a violation of the combustion of the mixture in the cylinders, which is accompanied by a clear gain of vibration. Note, the appearance of DVS vibrations is not necessarily a trottery, since there are a number of other reasons why the engine vibrates strongly.
In the list of major malfunctions, resulting in the engine Troit, marked:

Supply of insufficient or excess fuel into the cylinder;
supply of insufficient or excessive air;
Faults of the ignition system, early or later ignition;
wear or motor breakage, which is accompanied by a decrease in compression;
In other words, the engine begins to trim as a result of an inappropriate composition of the fuel and air mixture, late ignition of the mixture or lack of opportunity to set fire to the charge, as well as violations of the conditions of normal combustion of the mixture as a result of mechanical wear or versions of the engine itself.
Based on this data, you can narrow the search for the search and number of systems for diagnosis. You should start checking from the fuel system and the injector, then the air supply is checked on the inlet and the ignition system. In some cases, the engine trimming can also be the result of a failure of one of the ECD sensors.

Engine Troit: Violated ignition of fuel and air mixture

Most frequent causewhich makes the motor troit is later or early ignition, as well as a weak spark of spark plug. At the initial stage, unscrew the spark plugs for a detailed inspection. If the insulator damage or other defects are noticeable, then the candle should be replaced.

In the case of a damaged insulator, the place of damage is clearly visible, since this area is black. You should also pay attention to the state of the central electrode and estimate the gap of the side electrode.
Next you need to check the candle wires. An indirect attribute pointing to this element is the episodic turret of the motor in conditions of high humidity (rain, dampness, etc.). After warming up and outlet of the motor operating temperature Symptoms can completely disappear.

Starting with the inspection of the Cap Candle and the highest voltage wire. These elements are insulated with rubber, which has a property with time to rehash and crack, resulting in a wire begins to break through.
Also, the high-voltage wire or cap is often damaged during the execution of service or repair work In the windscarette space. We add that the breakdown's place is visually not detected. In this case, it is better to check this element of the ignition system by one of the available methods.
If everything is in order with candles and wires, then the culprit is that the engine troit can be the ignition coil. On motors with separate coils for each candle, this phenomenon is especially common. To check the ignition coil, you must unscrew the candle, attach to the mass and start the engine. Please note that the carving of the candle should touch the mass tightly, the cap must be tightly on the candle. Ignoring these rules can lead to burnout coil or switch. A good spark with a characteristic crackling will be evidence of the health of the coil, the lack of spark will indicate the need to replace the coil.

As for the electronic ignition distributor (switch), this element is broken not often. To check the candle, they are securely attached to the ground, then the caps are connected to them, after which one person twists the motor starter, and the other evaluates the strength of sparks on the candlelight.

Motor Trojection: Air Surveys

Insufficient air supply on the inlet or excessive amount can also cause troops over the cylinders. The air supply system may lose tightness and the engine begins to sue the excess air. The computer does not take into account this subsidence, as a result, the stability of work is violated.

Check the air system simple enough. It is necessary to close the inlet tube close to the air filter, after which the air to create a pressure of about ½ atmosphere, after which look for leakage. In case the pressure does not fall, then the system is sealed. The appearance of the hissing sound of the exit air allows you to determine the problem area through which the motor sues is superfluous.

The shortage of air often occurs due to the contaminated air filter, which has lost bandwidth. The filter must be removed and evaluated the operation of the engine after removal. Also, air may not be enough if the throttle is clogged or caused problems in this node. The specified element requires mandatory cleaning and verification. It is advisable to do this on each planning that is parallel to replace. motor oil, filters, etc.
Another cause of the engine trimming may be DPDZ, DMRV or another sensor, which supplies an incorrect signal to the ECU. The control unit in such a situation does not know what a degree is really open the damper, how much air actually entered the engine, etc. On the basis of the incorrect data "Brains" cannot accurately calculate the optimal composition of the fuel and air mixture in relation to the dynamically changing modes of the operation of the engine.

In this case, you should view sensor readings and read the scanner errors that connects to the car diagnostic connector. Then the values \u200b\u200bmust be compared with nominal. Deviations from the norm in the readings of the air-sufficient one or the throttle position sensor lead to the fact that the engine begins to trim.

Trojections for cylinders: faulty power system

During the system check, you should pay attention to the following nuances:

Fuel pressure;
air surface;
The fuel pressure directly depends on the health of the electric fuel pump, which is on modern injector cars located in fuel tank. The device may be clogged with a fuel pump filter mesh, problems with an electric motor of the fuel pump or power supply to the pump can occur. It is also worth checking the pressure regulator valve in the fuel ramp. Low pressure in the fuel supply system is often the cause of trim.

The next step will be to check injector injectors. This element has the property to be clogged, resulting in a capacity of the bandwidth, the form of the torch spray, etc. is disturbed. Also should not exclude the release of the injector itself. For cleaning and checking nozzles, you can use the flushing stand on which the special is pumped through the device washing fluid And the power is served. In such conditions, the operation of the engine nozzles is simulated, performance is evaluated, etc.

You can also check and clean the nozzles yourself. To do this, the device also pumps liquid (for example, a carburetor cleaner). Power supply is fed simple schema With a light bulb from the Accord terminal.
A good nozzle should not flow in a closed state. Also, the injector should be opened in a timely manner when the electrical pulse is applied. It is not allowed so that the nozzle is listed fuel, since the effectiveness of the subsequent combustion of the charge in the cylinder depends on the quality of the sceneling.

If the fuel pressure and the injector itself is in order, then you should check the computer. The control unit itself fails to be late, but this is possible. More often this happens in cases where the factory firmware changed when installing a HBO or a motor, a software chip tuning was done. Unprofessional manipulations S. fuel cards Can lead to the fact that the computer overflows fuel and pours spark plugs.

Reduced compression in cylinders

The compression drop indicates the engine malfunction or its wear. One or more cylinders are partially or fully operated, so fuel and air are supplied, but the mixture is not compressed properly. In this case, normal combustion does not occur. The compression drop occurs due to the slope of the pistons or valves, the strong wear of the piston rings and other defects of the BC, CBC or the timing elements.

In this case, it is necessary to measure the compression in the engine, after which the unit is disassembled for detailed diagnosis and repair. At the end, I would like to add that the operation of the motor with a non-working cylinder is prohibited, since riding with such a malfunction leads to the emergence of a number of additional problems, which greatly complicates and makes more repairs more expensive.

Missing. All drivers know this problem, only on a people's mechanical slang, it is called a little differently.

Does one cylinder not work, what to do?

"Troit engine" - just that is the name of the fault when it does not work in the engine. There are cases when two cylinders do not work, immediately. But it happens very rarely. Therefore, we consider in detail the situation with when one cylinder does not work.

Moreover, the causes of malfunction, their search and elimination, to the same extent refer to the situation when two cylinders do not work.

What features do you learn that one engine cylinder does not work? And everything is simple. According to the vibration of the body, interruptions in the working cycle and the strange sound differing from uniform engine operation. You will understand. If the engine is troit, it is impossible not to notice on the behavior of the car.

The driver has little familiar with the device and principle and the question itself, - is it possible to move (more than a long time to ride if one cylinder does not work).

In principle, yes, you can. But, it will last long. The engine will fail or you "go" to yourself problems with the engine, the number of which will make you to upset not on the round, but on a frowning figure.

Before analyzing the reasons why one / two cylinder may not work, briefly consider the consequences of neglecting this malfunction.

What makes movement with a non-working engine cylinder

Fuel, entering a non-working cylinder, does not burn. It is mixed with oil. Washes it from the cylinder mirror and enters the crankcase. Not only is the dry surface of the cylinder undergoes mechanical damage, the so-called. Zadira and oil diluted with gasoline does not perform its functions on the lubrication of the remaining cylinders.

This, accordingly, also leads to the failure of the remaining cylinders. That is, and maybe, you are 100% secured.

Another unpleasant news, if one cylinder does not work - the possibility of overheating the engine with all the ensuing consequences. The engine begins to change temperature mode. It is heated, because the oil has lost its quality, and it is in addition to lubricant, performs the heat sink function.

Probably, there is enough consequences in order to think about, - and is it possible to continue to ride if one cylinder does not work.

Where to seek the cause of the non-working cylinder

Remarika is such that checking and the search for the causes are carried out in the conditions of the garage. There are two options: mechanics and electrician (ignition). You need to start going on an easy way, namely from the ignition diagnosis.

• Spark plug. Determine their health in the old manner. Visually side electrode and insulator should be light brown, but not black with ingar flakes. The wedgened electrode speaks either about the mixture too enriched, or it spatshes it with oil. Sparking. By inserting the candle in the BB of the wire to bring it to a distance of 1-2 cm to the cylinder block and make a scrolling starter. If the spark is the distance "Speaks", then the candle is fine, if not, then change.

• High voltage wires. Check them for mechanical damage. Check their tips. If there is a light gray flap on the tip of the wire, it indicates its operation in extreme mode. The resistance of the wire wiring is checked by a multimeter. On the different engines Different Wiring Wire Length and Miscellaneous Resistance. If the other is not said, then 20 com by the permanent resistance value. If the resistance is higher, you need to look for the cause in the Wire BB.

• Distributor. If the candle is faulty, we will see "breakdown" in the ignition distributor lid. We definitely check the "Corner", you can slightly stretch the spring.

• Bentally confused wire wires. And precisely because of this, one or two cylinders do not work.

• Injector. It is possible that one cylinder does not work due to injector problems. This is either a malfunction of the nozzle itself, or the injector has been clogged by poor-quality fuel, or rather what there is a lot in it. By the way, be careful and picky when using the "Super - Miracle" of fuel purifiers, which are sold at each corner. Ideally, the diagnosis and cleaning of nozzles should be carried out on the stand.

• Timing. Fuel - the air mixture enters the cylinders in the wrong amount and incorrect quality. Here are the causes of mass. The belt is incorrectly installed, the production of tensioners, gland. Developing distribution Vala, wear of hydrocomathers. It turned rooted, as a rule, because of the engine overheating (carefully look at yourself when you want to ask - why it overheated) during the sports style of the ride, or reducing the coolant level.

These are the traditional reasons for the fact that one engine cylinder does not work. And this is another incomplete list. In any case, the search for the reason will lead you to the desired result, and you will eliminate this malfunction. Alone either with the help of the service.

Good luck to you in determining the cause and elimination of the malfunction of the non-working cylinder.

If the engine is unstable, then such a phenomenon is called "Missing". For our ear, the word is overseas and not for everyone. Experienced motorists know what it is. Missing - skipping the ignition of a combustible mixture in one of the cylinders. More often drivers in this case say that the engine troit. In this article, find out which causes of the occurrence and what ways to eliminate the defect are possible.

Engine Troy is accompanied by "Creation". The sound is completely distinguishable and recognizable. It is he who signals about the non-working cylinder. Engine temperature quickly rises. . Power unit is subjected fast wear. Therefore, it is important to determine why the engine troit and as soon as possible to eliminate the malfunction.

Spark plug

They are the most common cause. Even if the candles changed not so long ago, unscrew and inspect.

It has a properly working candle, there is no black nagar on the electrodes and insulator. The body of the candle is white, without strips and points of black. The presence of defects indicates that the ignition candle breaks the discharge and it will not work correctly. Nagar prevents the normal formation of the spark and the engine to trim.

Nagar on ignition candles electrodes - the main cause of the engine of the internal combustion engine.

The second reason is incorrectly chosen candles. Buy recommended car manufacturer. Too big or small gap leads to a failure to work one or more cylinders.

High voltage wires

Check high voltage wires Mandatory when diagnosing the engine when it troit. They should not be traces of breakdown. Candle tips must be clean without a car.

After visual inspection of the candles, check the high voltage wires. They should not be traces of breakdown: black dots and stripes. Due to breakdown, the current does not reach the candles. This defect is the following cause of the engine of internal combustion.

Independent check of wires will not cause difficulties. They are tested by the usual multimeter. It is necessary to measure the resistance of each wire.

Videos check wires

Check the wires by the device multimeter. Measure the resistance of each wire. It differs in different brands of the car, but does not exceed 20 com. Good wires have the same resistance. If one of them shows much less or more, then it is faulty and due to it troit a power unit.

Ignition module

The ignition module is often the third cause of the strength of the power unit. You can check it, but on special equipment and in the presence of experience. You should not test the module on your own.

Ignition Module Videos

Engine TROIT only on cold

There are cases when the engine troit on the cold. If you made sure that the candles and wires are in order, then check the ignition module. Without skills and sufficient experience, such a diagnosis should not be carried out.

You can get a shock or burn the module, the engine control unit.

If suspected that the engine's trimming occurs due to the malfunction of the ignition module, then refer to the help of specialists.

Injector fault or nozzles

Injector motor Troit in such cases:

1. Injector is defective, but this is very rare.
2. Write bad gasoline or incorrectly used the fuel system cleaner.
3. Clogging injectors.
4. The electrical power circuit nozzles has a break or closes.

Eliminate such faults will help the engine diagnostics and competent motorist. For independent check Injector and nozzles need experience and special equipment.

Low compression

Troop the engine due to insufficient compression in the engine cylinders. The decrease occurs: when rolling the rings on the pistons, the valve burned. Some cars are allowed to adjust the valves. Incorrect gaps - the cause of the injection engine.

Finally

If one or several cylinders do not work, do not hurry to go to computer diagnostics. The scanner check will lock the ignition skip, but does not indicate the cause of the occurrence. The cylinder does not work - it is so obvious. Before riding the car service, check the candles and wires. They are most often guilty in the fact that the engine Troit.
