Hi there im new to this forum, i have just bought a MK3 gti 8v N reg and its over fueling plus missing on low revs (wont idle) clears off and revs above 3000rpm ecu has been checked and airflow meter aswell both given the all clear. i was told by vw it was the throttle body so i had it replaced and the car still does the same any suggestions would be greatly appreciated , thanks simon.
