hi guys so I have a 1995 Camaro z28 lt1! so my car is missing still. so I checked for vac leaks there was one I fixed it. I changed fuel filter put fresh gas in put all new spark plugs in. I dident change my wires yet. so what I did was I pulled each injector connectors off one by one. and when I pulled injector connector off #3 the car rpm dident change at all. is there anyway else I can check for a bad injector? to see if its pulsing. or do you think it can be the spark plug wire any help please!
