There is a problem with the ignition coil or spark plug [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

He will also affect the carbon deposits of the valve, in one of which is the water temperature sensor. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, if you want to check that cylinder is missing and then replace the ignition coil I hope my answer will be helpful to you, if you don't understand, please ask, I wish you a safe journey [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello measuring the cylinder pressure of the car [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, if it is a cold car, the fault phenomenon is obvious, and the hot car phenomenon has been improved. It is likely to be caused by excessive carbon deposits, to computer or decoding to read out the fault is insufficient combustion, in the case of excluding spark plugs, ignition coils, it is recommended to do carbon deposition cleaning, serious carbon deposition can consider removing the intake branch pipe cleaning, pipeline and valve seat. Cars with a small number of kilometers can consider adding 97 or 95 gasoline and pulling the bottom gear at high speed.

Hello, check the ignition coil and spark plug, they are generally caused by it.

The cause of the engine fire and the symptoms of the early occurrence of Zhensun.

Engine cylinder lack and misfire is a meaning, but the name is different, cylinder lack and misfire both refer to a cylinder or multiple cylinders in a multi-cylinder engine does not work or can not work normally; After the failure of missing cylinder misfire, the engine will have severe shaking, resulting in insufficient power, weak acceleration, high fuel consumption, and if it is a multi-cylinder misfire, the engine may not start.

Special attention should be paid to the fact that some cars will still inject fuel from the fuel injector when they lack cylinders, so that the unburned gasoline mixture enters the exhaust pipe and continues to burn where the three-way catalytic converter is located, resulting in the three-way catalytic converter being scrapped due to high temperature.

The causes of engine misfire can be divided into two main categories.

1. Failure of the electronic control system, such as sensor signal loss or signal inaccuracy, wrong control signal or no signal output, failure to ignite due to damage to the spark plug or ignition coil, no fuel injection from the fuel injector and line failure, etc.

2. Mechanical failure, mainly due to insufficient cylinder pressure, such as valve closure is not tight, air leakage, the gap between the cylinder, the piston, and the piston ring is too large, resulting in insufficient compression ratio in the cylinder.

The lack of cylinders in the engine will bring great harm: the speed and power of the engine will decrease. Increased fuel consumption and emissions of pollution. Aggravate the wear of the running parts and shorten the service life of the lubricating oil. The engine is missing cylinders and needs to be overhauled in time.

The solution to the lack of cylinders in the engine:

1. Circuit failure: spark plugs, cylinder wires, ignition coils, etc. are damaged, and it is easy to lack cylinders. You can use the broken fire to determine which cylinder parts are damaged, and replace the damaged parts;

2. Oil circuit: If the oil circuit is not cleaned for a long time, there will be more gum and magazines in the oil circuit, and the fuel injector will be blocked. The oil cut-off test is used to detect the fault point and carry out maintenance;

3. Mechanical failure: The internal piston, connecting rod, piston ring, piston pin, etc. of the engine are faulty, which will generally be accompanied by obvious abnormal noise, and obvious metal chips can be seen when detecting the oil. Generally, this situation requires the engine to be dismantled.

1. Gasoline should be soaked in gasoline to dissipate heat, in addition, the oil volume is too low, which may also affect the oxygen sensor of the exhaust system, these parts are not cheap, so do not exceed the bottom line before refueling.

2. Engine oil Generally speaking, the consumption of engine oil is not serious and is enough to survive the cycle between maintenance, but in summer due to the hot weather, the oil consumption will be a little higher than usual. If it is found that there are impurities or gasoline smell in the engine oil during the daily inspection, and the exhaust smoke is light blue, it means that there is a problem with the engine, and the parts may be abnormally worn, so you should enter the factory for maintenance as soon as possible.

3. Transmission oil.

When you change your engine oil, you can check your transmission oil by the way, and since the inspection process is more cumbersome, you can ask the dealer's service department to handle it. In order to measure accurately, the car must be discharged into neutral p, run at idle speed, and parked on a flat place, and the oil must run to an operating temperature of 80 93.

Too much or too little oil can damage the gearbox, and too much oil may cause excessive resistance to the operation of the parts, or cause the transmission oil to bubble and deteriorate, resulting in abnormal wear and tear of the parts. So when you check your transmission fluid, it's important to measure accurately.

Fourth, the power direction oil.

When the engine cools down, wipe the top of the oil filler cap and the oil reservoir clean, then unscrew out the direction oil cap, and wipe the dipstick clean with a fiber-free clean paper towel, and then install the lock, and then open and pull out the oil level to check the dipstick.

C4 Sega occasionally lacks cylinder jitter, generally speaking, the quality of the gasoline used in the car is poor, it is indeed possible, and then it depends on whether the throttle valve of the car needs to be cleaned, whether the spark plug needs to be replaced.

First of all, the oil was changed, and there was no improvement. Go to the computer and read the fault code. Considering spark plug discharge capability? Is the cylinder pressure normal? Conclusions are generally drawn.
