My friend has a car. This happens from time to time, but not often. Go to the 4S shop for inspection. The idle speed of the car is normal. The fault code of the 4S inspection is: there is a cylinder on fire. It's gone.

Generally speaking, 4S stores will let the spark plugs be replaced. Actually, it's just making some money. Just clean up the carbon deposit on the electrode.

A knowledgeable friend said: it may be that the throttle is accidentally stuck. Suggest adding better oil. If the fault light is on and the negative wire is broken and then connected, it can generally be ruled out.

If this kind of fault often occurs and the engine works rudely, it is best not to drive for a long time to avoid three-way catalytic poisoning caused by combustion deterioration.

Personally, I suggest cleaning the accelerator or sending it for repair as far as possible without other sensor fault codes.
