How to solve the car idling jitter

The solution of vehicle idle jitter is as follows:

1, the engine has a serious carbon deposit, and the most common reason for car jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit. 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, ignition coils, the ignition system is not working well, and the spark plugs are not in good condition, which will also lead to this failure. Solution: check whether there is too much carbon deposit in the spark plug and replace the spark plug;

3. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle has been cleaned, the oil pad and spark plug have been replaced, and the body is still shaking at idle speed. It is recommended to go to 4S shop to check whether the fuel 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;

4, engine parts aging, car jitter is also related to the aging of engine feet (also known as claw pads). The engine foot is actually the damping system of the engine. The engine foot is responsible for absorbing slight vibration when the engine is running. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter. Solution: Replace parts.
