If the new engine support has been replaced, or there continues to be shaking phenomenon, then there are more reasons for this situation, if the steering wheel and the body are obviously shaken during the driving process, you need to check whether the tire is excessive wear, whether the tire pattern is deformed, and do four-wheel dynamic balance.
In addition, check whether the ball cage sleeve of the half shaft is damaged and check whether the half shaft is deformed.
If it is in place, it also produces jitter, this situation, such as the gasoline oil quality is not good, the gasoline oil is poor, the deflagration can not meet the normal requirements, the carbon accumulation inside the throttle valve is increased, the spark plug gap is too large, the ignition performance is poor, or the ignition coil is damaged, the engine cylinder pressure is insufficient, the engine cylinder pressure is not uniform, these reasons will produce the force jitter.
