1995 Grand Cherokee 4x4 5.2L V8. It is always fine on a cold start, and sometimes it won't have any issues all day. Occasionally when warm it will start to idle really low, stall out sometimes, run rough, jerky etc. I have a brand new O2 sensor, IACV, fuel filter, O2 sensor, and TPS sensor already installed on the vehicle and nothing seemed to help. I was thinking maybe the fuel pump but it only happens when warm so I don't think that is the case. CPS maybe? Anyone have a similar issue?
