Hi guys. I did post some time back about my golf 3 gti 94mod. It was overfueling . Missing. Cuttn off at times. Didnt wana rev up sometimes etc. The fuel is also burning very rich. Diagnistics picked up airflow meter and next to it says short circuit to earth. Wer can I get another airflow n hw much will it cost. N if its better to change managment then wat wud b the best for my car n wer can I get it n wat would it cost.
