Volkswagen Tiguan Throttle Jump

1, engine carbon deposit is serious. The most common cause of automobile jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit.

2. Ignition system problem.

3. The oil pressure is unstable.

4, engine parts aging. Car jitter is also related to the aging of engine feet. The engine foot is actually the damping system of the engine. The engine foot is responsible for absorbing slight vibration when the engine is running. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter.
