I have a 98 GC 4.0L 75Kmiles. I completely serviced all fluids, plugs,
wires, cap & rotor. We get a caughing hesitation when cold, during low RPM
runs. When warmed up there is no low rpm hesitation. I tested & replaced
the coolant temp sensor according to Haynes, have not done the PCM
diagnostic reset. Have disconnected the battery. Still getting the
hesitation. Could this be due to not an actual PCM reset, or a throttle
position sensor or something else. Please help
