1991 Saturn SL1 1.9L Poor Idle Quality, Stall
Posted to GM Driveability on 10/10/2007 11 Replies

In open loop car will die at idle. In closed loop it will idle but it's rough. The car hesitates real bad after it's in closed loop. Have to keep the RPM over 2000 to drive while it's in open loop. It idle fine with propane. There are no external vacuum leaks....
