2000 Jeep GC rough idle
After a water pump failure and over-heat, the jeep runs rough only at idle. 190k and 4.0. Code says misfile on cylinder 1. I put in new plugs, coil pack and injectors. No change. runs fine at anything over idle and starts fine. Idle seems a bit worse when hot. No sign of any head gasket issues. Any suggestions?
