Porsche cayenne shakes after the throttle plug is pulled out.

Spark plugs are caused by mismatch after cleaning the throttle. According to car home's information query, the reason why Cayenne shakes after dialing the throttle plug is

1. If the spark plug is not replaced for a long time, the grounding electrode of the old spark plug will be seriously ablated and the gap will gradually increase. These changes will affect the ignition effect.

2. It is caused by no matching after cleaning the throttle. Idle speed of electronic throttle is realized by stepping motor driving throttle blade to rotate at a certain angle. After turning a certain angle, there is a gap between the main throttle port and the flap, and the idle intake port gradually accumulates in this place.
