Hi new to the forum but thought I should share my experience with a P0101 code, check engine light and erratic idling.
Tried new MAF, O2 sensor, PCV ( a bastard of a job), and leak testing, all with no success.
Finally removed the throttle body, removed the 6 cover clips, and cleaned the position sensor/potentiometer with contact cleaner. Sorry no pic but its clear when you take the cover off
Great success!!
car is C200 Kompressor with m111 engine.
Hope this helps someone.
