My 1991 Camaro RS (v8/305) will start up fine but when I push on the gas it will sputter and sound like miss fires along with backfire. I replaced the fuel filter, EGR valve, PVC valve, fuel injectors, distriputor, and button, along with spark plugs and wires any information would be helpful I took it to firestone and had a computer test on it thats how they caught most of the problems

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
