It could be a failed Knock Sensor. The knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. A knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. Don't wait until additional problems occure, replace that failed sensor in your 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997 Firebird before it's to late. Use the same sensor the factory used when your car was new.
