My dad just bought an Firebird and it keeps backfiring. He keeps ajusting the timing by moving the distributer cap, but it isn't getting any better. It backfires really bad when you hold the accelerater down. It sounds like making popcorn almost when holding the accelerater down. My dad want's some ideas on what to do to get it to stop backfiring. The distributer cap is new, it has new wires, the spark plugs aren't new, but they do look good. So if anyone has any idea on what is wrong please help, thanks.
