4.0 idle problems
I bought a 95 yj 4.0,5 speed with a burnt engine wiring harness, I put on a new harness it fired right up, I've put probably around a thousand miles on the jeep and it's run great until the other night. I was on my way home and about half way there I noticed my rpm drop and no throttle responce then it picked up and dropped again at stops it would've probably stalled if I didn't keep my foot on the gas it did this the rest of the way home. So today I pulled the throttle body off cleaned it and the IAC, same problem. I bought a new TPS and IAC and put them on and it actually seems worse, any ideas on what else it could be?
