PERIODICALLY WHEN I DRIVE MY GRAND AM IT WILL ACT UP. AFTER DRIVING APPROX. 15 MINUTES THE CAR WILL JUMPS IN RPMS AND THEN ALMOST STALL. SOMETIMES THE SERVICE ENGINE LIGHT WILL COME ON AND SAYS MASS AIR FLOW SENSOR.I HAVE REPLACED THIS AS WELL AS THE AIR IDLE CONTROL VALVE, THE THROTTLE POSITIONING SENSOR, THE EGR VALVE AND THERMOSTAT, I ALSO FIXED CATALYTIC CONVERTER. I AM STILL HAVING SAME ISSUE. NOTHING HAS HELPED. COULD IT BE ELECTRICAL ISSUE OR SOMETHING NOT CONNECTING? I HAVE NO CLUE WHAT TO DO NEXT
have the same problem?
