well when my 1989 CHEV CAMARO IROC-Z is idling or even when you rev the engine you feel like a roughspot then goes away then again and so on its there all the time i was wondering if i can get some tips on what it might be

 

Are you running an aftermarket chip. Hypertech, etc? If you have modified the car in any way it wont run right

 

nope stock

 

I had/have a similar problem. Through process of elimination, I have decided its probably the injectors. Let the car warm up then turn it off and ohm the injectors hot. If your numbers aren't in the 15-16ohm range you know you have bad injectors.

Just fyi my injectors ohmed out well, but they dont spray well which has given me problems. so what im saying is even if they ohm out well, they still could be contributing to your problem.

Good luck!
