1996 Pontiac Firebird 3.8L Misfire, MIL Lamp on
This car has a miss at idle and only at idle. Plug on #4 has been changed twice and the wire too. Injector waveform look good. If you raise the idle the miss stops. Also the missfire counter confrims this. I'm wondering about an intake but search doesn't show ...
