Why do lifan 520 cars sometimes tremble?

Lifan 520 cars sometimes tremble for the following reasons:

The throttle valve is too dirty, and the fuel injector has too much carbon deposit. After a certain mileage, a dirty throttle will cause the throttle to close loosely or the idle stepper motor to get stuck. Therefore, when the vehicle is shaking, first check the throttle and fuel injector. If the throttle valve is found to be too dirty or the fuel injector has too much carbon deposit, it should be cleaned in time.

Engine pad aging, car jitter is sometimes related to engine pad aging, pad is actually the engine damping system, responsible for absorbing the slight jitter when the engine is running.

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

The aging, deformation and jitter of running automobile tires are far more worrying to drivers than idling jitter. Therefore, after the tire is aging, the owner should replace it with a new tire in time to avoid causing greater hidden dangers of accidents.

In addition, if the owner is used to sudden braking and emergency stop, the brake disc will be uneven, resulting in uneven stress on the brake disc and vehicle jitter.
