I have a 94 chevy lumina 3.1 208,000. When I accelerate it hesitates and stumbles and sometimes it dies. While trying to give it gas it occasionaly backfires. I have changed fuel pump, fuel filter, plugs, wires, egr valve, tps, idle air control valve, knock sensor, pcv valve and all vacuum hoses, crankshaft position sensor. It doesn't sound too bad when idling it just won't go anywhere. Can somebody PLEASE help me? I am thinking it might be the computer?
have the same problem?
