1, too dirty throttle or too much carbon deposit in injector will cause engine jitter.

2, spark plugs, high-voltage lines and ignition coils, after working for a certain period of time, the ignition system will not work well. Solution: Check the working conditions of spark plug, high voltage line and ignition coil, and replace the spark plug.

3. When the vehicle starts, the engine will shake more than usual, and sometimes it won't even start once. Solution: Clean the oil circuit and check whether there is carbon deposit in the idle motor to be cleaned.

4. After the car runs for a period of time, the dirty throttle will lead to the untidy throttle closing or the idling stepper motor being stuck, which will lead to the high idle speed of the engine. The carbon deposit produced by the engine during the working process will also cause vehicle jitter. The causes of automobile engine jitter are as follows:

1, too dirty throttle or too much carbon deposit in injector will cause engine jitter.

2, spark plugs, high-voltage lines and ignition coils, after working for a certain period of time, the ignition system will not work well. Solution: Check the working conditions of spark plug, high-voltage wire and ignition coil, and replace the spark plug.

3. When the vehicle starts, the engine will shake more than usual, and sometimes it won't even start once. Solution: Clean the oil circuit and check whether there is carbon deposit in the idle motor to be cleaned.

4. After the car has been driving for a period of time, the dirty throttle will lead to untidy throttle closing or the idling stepper motor being stuck, both of which will lead to high engine idle speed. The carbon deposit produced by the engine during the working process will also cause vehicle jitter. The causes of automobile engine jitter are as follows:
