Sanyang Cruise 300 Idle Jitter

Idle speed jitter, the new car has been used for a while, and some car owners will find that the body is a little shaky, but they don't know what is wrong. "Body shake" is a signal to tell the owner that there is something wrong with the car.

This may mean that the vehicle has the following three situations:

(1) The most common cause of vehicle jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit.

(2) Check the working conditions of spark plugs, high-voltage lines and ignition coils. The ignition system is not easy to use, and the spark plug is not in good condition, which will also lead to this failure.

(3) If you clean up the engine carbon deposit, clean the throttle, change the oil pad and spark plug, etc. You still find the car body 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.

(4) Car jitter is also related to the aging of engine feet (also called 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.
