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
