1989 Buick Century Custom 3.3L Misfire
Posted to GM Driveability on 10/1/2004 7 Replies

This thing has a misfire, worse on cylinder #2 but somewhat reflected on #5 (companion cylinder but seems to share nothing else but the coil). I feel a little stupid that I can't figure this thing out. It seems to be lean on #2 and the O2 waveform cycles at 5....
