Well the Jeep is purring like a kitten.
I swapped the IAC & TPS before the last trip, last night I swapped in a new MAP sensor. Jeep has never ran so smooth...
Anyone got any suggestions for other 20 year old sensors I should replace while I'm at it? I thought about replacing the IAT?


Also, I finally replaced the very first part that every broke on the Jeep...
A little back story:
I got my XJ right after I turned 18, "Back when I knew it all", I wanted a big 6 cyl, 4wd, and 4-door for college. The XJ was my answer. I bought it from a dealership as it had low miles and was really clean, so it came with a warranty. "First Mistake"
When I got it home, My Dad & I decided to change the oil... We successfully snapped off the Oil Sending Unit, also we noticed an oil leak under the Jeep. Since it was under warranty I took it back.
This is where my life lesson comes in:
The mechanic said, "The oil leak is just coming off the back of the plug, I put a bigger gasket on it's good to go now... Also since you broke the sending unit you'll need to pay for that, I just happen to have one so your in luck."
When I got back in the Jeep and cranked it up the Oil Pressure Gauge read over 80PSI, laughing the mechanic said, "That Jeeps got GREAT OIL PRESSURE!"
Thus began my quest for greater knowledge & Jeep Wisdom. This lead to the first Jeep repair as the "Oil Plug" was still leaking. The leaky oil plug turned out to be a cracked weld in the oil pan where someone had obviously tried to do a self repair. So first thing to get fixed on my heep was replacing the Oil Pan. I always left the Oil Pressure Gauge Broken as a reminder. Yesterday after 7 years, I finally felt I'd learned my lesson and I fixed it.

I think that was before I started this thread, I carry a spare now. I've also since replaced the O2 unit.
I'm trying to think of things that the Jeep still would function but not optimally as the case with, MAP, TPS, & IAC. If the CPS goes your stranded.
