What are the causes of automobile engine jitter?
Solution: clean the oil circuit, check whether there is carbon deposit in the idle motor, and clean it.
2. Ignition system problems Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to such failures.
Solution: Check whether the spark plug has too much carbon deposit and replace the spark plug.
3. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, and the body is still shaking at idle speed. I suggest you go to the 4S shop to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is wrong, the car body will shake.
Solution: Check the oil pressure and replace parts if necessary.
