Some history:
My 98 XJ has 200 000km on it.
It got new plugs and Accel wires in the last 6 months.
It has an older Optima Yellowtop battery.
The problem:
Recently on a short highway trip my Jeep started to stumble. It would run fine for 10min at a time or so, but then it would start to miss for a bit... maybe 10-15 seconds at a time it would just run rough. It got worse and worse during the trip and would stumble and miss for longer periods of time. Then I had my CEL come on... I pulled over and checked it and it was my TPS showing high (or low maybe, I can't remember) voltage. I reset the CEL and cleared the code. I started my Jeep and drove home without any more issues.
When I got home, I swapped my TPS out with my brothers (his was new a week before). After that, my Jeep would take forever to start... it would just turn over and over but if I let go of the key and let the starter wind back down, then tried again, it would fire right up the second try. It did that very consistently for about a week. First try... nothing, second try, fire up fine. I gave my brother his TPS back, thinking it was messed up somehow. Installed another TPS I had in the garage and it has been the same ever since. First try nothing, second try it starts fine.
Help??
I have no idea what's going on... I have tried 3 different TPS's with no luck. I haven't had a CEL come on since that first time on the highway. I would like to get this fixed soon as this is my DD and I'd like to get this fixed before winter hits up here...
Thanks in advance!
