What should I do if the vehicle suddenly shakes while driving, and then the engine fault light comes on?

1. Dirty throttle will cause idling jitter.

2. Spark plug failure will lead to vehicle idling jitter.

3. If one cylinder of the engine does not work, it will also lead to idling jitter, and the vehicle will also shake when the vehicle accelerates at low speed.

4. The rubber parts inside the engine bracket and the gearbox bracket are aging, which leads to vehicle idling jitter.
