I HAVE A 91 CUTLASS, 3.1 V6 I HAVE REPLACED THE SPARK PLUGS, WIRES, IDLE
AIR CONTROL, MAF SENSOR, ECM, FUEL PUMP TWICE, FUEL FILTER, HAVE RUN
INJECTION CLEANER IN IT, DRY GAS AND THE PROBLEM IS WHEN IT WARMS UP IT
BEGINS TO IDLE ROUGHLY AND SOMETIMES STALLS THIS CAR ONLY HAS 30000 MILES
ON IT AND IS REALLY IN GREAT SHAPE
BUT THIS HIT AND MISS IS GETTING VERY EXPENSIVE.DO YOU HAVE ANY
SUGGESTIONS? THANKS

My 91 Cutlass supreme did the same thing. I finally tested the injectors
and found one dead and one dying. After replacing the bad injectors the
engine ran fine.
