Cool car, Santa Claus, the first idle car is flashing.

1, firstly, 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 car body is still shaking at idle speed, it is recommended to check the fuel supply pressure and intake pressure sensors at the 4S shop. 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. The best solution is to check the oil pressure and replace parts if necessary.

2, followed by engine parts or aging, such as engine foot aging may make the body shake. 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.

3. The engine throttle is too dirty, or the fuel injector has too much carbon deposit, causing jitter. When there is too much carbon deposit, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which leads to too thin mixture during cold start and difficult start. However, the gasoline adsorbed on the car carbon deposit after landing will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture rich, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter. The solution is to clean the oil circuit and check whether there is carbon deposit in the idle motor, which should be cleaned.
