What causes the small forklift truck to vibrate when it deviates?

1. The most common cause of serious engine carbon deposition leading to vehicle jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposition. When the engine has too much carbon deposit.

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.

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 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.

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.
