Hi All,
Have an 02 3.7L with around 93k on it now. About 10 months ago I replaced the TPS due to erratic idling and occasional hesitation when driving (I did the key trick to get the codes so knew the TPS to be the cause). I also cleaned the IAC at the same time.
It's ran like a champ in the interim until last week. Family and I were about half way through a 600 mile trek to Outer Banks in NC when there was some violent jerking which lasted a few seconds, went away, came back again a few minutes later. CEL light came on so I pulled over and checked the codes (p0121 and p0123) which leads me to conclude that this is a recurrence of the previous problem. I removed the TPS wiring connector, blew in it to remove any debris and replaced it. No further recurrence (and CEL light eventually went out) until a week later when we were half way through making the return trip. The KJ hesitated abruptly a couple of times and then was fine for the remainder of the journey. This last hesitation occurred just as a heavy rainstorm started (not sure if that is relevant).
Does anyone have any suggestions as to why this problem may be recurring other than my 10-month old TPS has gone bad (which seems unlikely). The truck is my wifes daily driver and I don't want her to end up getting stuck somewhere in the current 90 degree heat.
Any help greatly appreciated as always.
