1999 Oldsmobile Cutlass GL 3.1L Poor Idle Quality
Posted to GM Driveability on 5/30/2003 9 Replies

Can create a small vacuum leak and idles smooth and long fuel trim goes to about -1 to +1. Have checked for vacuum leaks-none found. Oxygen sensor seems to be working properly.I also cleaned throttle body and IAC.
