The cause of the car's vibration when accelerating.

The cause of vehicle body vibration during acceleration;

1. When driving, the engine jitter is normal, and sometimes it can't be started at once. It may be that the throttle is too dirty, and there is too much carbon deposited in the nozzle and air intake. In the case of cold car, the carbon deposit will adsorb some fuel. If the fuel does not completely enter the cylinder for combustion, it will cause the symptoms of unstable idle speed and difficult start.

2. When driving at high speed to a certain speed, the steering wheel can feel obvious jitter or jump, but it is not obvious at low speed. In fact, there are many problems that cause automobile engine jitter. First of all, we should eliminate the abnormal jitter caused by engine failure, because engine failure usually occurs at low speed.
