My car has had this miss/rough idle for awhile now. I'm thinking it might be the ECM. I pulled the plug on my CMP for the hell of it and the car idles exactly the same. I also did not get a CEL or any pending CEl. (I have a scanner) Also, when I deleted the cats I never got a CEL. Both of witch should have thrown a code right? Its a 94 3.8.
