Why does Arrizo gx accelerator pedal vibrate?

Generally, the engine jitter is too large, which is transmitted to the accelerator pedal. The possible failure points are as follows: 1. The engine is out of cylinder, resulting in one or more cylinders not working, and the engine jitter is strongly transmitted to the accelerator pedal. 2. The throttle of the engine is too dirty, causing the engine to shake. It is recommended to check the throttle. If it is too dirty, it needs cleaning. 3. The rubber parts inside the engine and gearbox bracket are aging, which makes it impossible to absorb the vibration when the engine is working, and the vibration will be transmitted to the accelerator pedal.
