Engine Performance problem
1997 Pontiac Firebird 6 cyl Two Wheel Drive
I have a firebird 3.8L V6 the is breaking up when engine gets hot after running awhile. It starts hesitating sputtering, missing, when accelerating, and under load. So far new parts: fuel pump, crank sensor, plugs, fuel pump relay, fuel filter, coil pack for cyl. 1 and 4. Starts and runs fine when cold, but starts erratic breaking up when engines heats up - like out of timing, runs rich (gas smell), also lost gas gauge when tank installed. Also, does put out any engine errors codes. Please help - any ideas?
have the same problem?
