Backfiring motor
I ran my car at the track Friday night and it was back firing so bad my friends were call me drive-by. I did a search about back firing and a lot of guys said it could be the coil? It has a new opti and I have not had it wet. It runs fines till you wot, then at around 4500 rpms it starts breaking down and back firing. Any thoughts.
