Need some help
I bought my 96 Camaro on monday, it has a 3.8L V6, it ran fine for a couple of days, then after it had been running awhile i was driving and stopped at a red light and all of a sudden it felt like it was going to die, had a rough idle, big loss of power and it responded late to the pedal and would kinda play out when id press the pedal like it was skipping or stuttering. Well one of the plugs on one of the coils was not making sparks so i replaced the coil, and all the others seem to be working fine, well i had my power back, but that stuttering was happening again. what could this be? the plug from the coil? a spark plug? Fuel injector? pleez help fast thanx
