Solution to the jitter problem of the ninth generation Accord D file

1. The most common cause of serious engine carbon deposition leading to vehicle jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposition. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head at the start of the cold car will be absorbed by a large amount of carbon deposit, resulting in too lean mixture at the start of the cold car.

2. Ignition system problems Check the working conditions of spark plugs, high-voltage lines and ignition coils. The ignition system doesn't work well, and the spark plug doesn't ignite.

3. The oil pressure is unstable. If you have cleaned up the engine carbon deposit, washed the accelerator, changed the oil pad and spark plug, you still find the body at idle speed.

4. The aging of engine parts and automobile jitter are also related to the aging of engine feet.
