My 19 18 Chang 'an small single platoon, why does it always shake when changing speed?

1, cold start jitter.

First of all, from the cold start, the main reason for the body shake during cold start is insufficient fuel combustion, which leads to insufficient power of the car.

2. The problem of shock absorption system.

Body shake is also related to the aging of shock absorber system. Mainly responsible for filtering out the vibration when the engine is running. If there is something wrong with the shock absorber, these vibrations will be directly transmitted to the steering wheel and cab, which will affect driving.

3. The tire problem.

For tires, wheel balance should be done when replacing new tires and rims, otherwise the steering wheel will shake easily when the counterweight is uneven.

4. Throttle problem.

The most common cause of automobile jitter may be that the throttle valve is too dirty and the fuel injector has too much carbon deposit.

5. The oil pressure is unstable.

The engine carbon deposit has been cleaned, the throttle valve has been cleaned and the oil cushion has been replaced. If the car body is still shaking after all this, I suggest you go to the repair 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, the numerical error and improper operation of the intake pressure sensor will cause the body to shake.
