1989 Pontiac GRAND PRIX 3.1L Poor Idle Quality, Cuts out, Stall
Posted to GM Driveability on 1/14/1999

Vehicle came in with extreme misfire. Diagnosed bad ignition module and coils. Car seems to be fixed, but after a few weeks, car is idling poorly and stalls out. No codes found. Fuel pressure good. Ignition system seems to be working fine.
