1996 Oldsmobile Cutlass Supreme 3.1L Poor Idle Quality, MIL Lamp on
Posted to GM Driveability on 10/7/2004 13 Replies

This vehicle runs fine, but idles poor. I have random misfires on most cylinders but mainly on #2. I thoroughly checked out the EGR system and found nothing. I don't think it is a fuel trim problem. Adding or subtracting fuel does not help. The O2 cycles well....
