    hi guys, getting hairless now with this. have a problem with my v6. Had apparent misfire when idling and acccelerating. Scaned for faults but none showed up. Replaced coil pack , plugs and leads. no change. Just replaced coolant sensor yesterday and the problem seems worse, idle is going up and down from 100 to 600. Checked all my vaccum pipes and all are ok. The car judders when accelerating in high gear occasionally hear a popping noise from the engine like an internal misfire. Exhaust seems pretty smelly as well. was going to replace my throttle body but thought id just ask on the forum first. Any thoughts plz. Desperate here. aLSO CAN FEEL THE ACCELERATOR PEDAL TWITCHING ON ITS OWN.

    you need VCDS to perform throttle body adaptation.
    Have you checked MAF sensor?
