Crazy thing... I went to honk my horn at a dog in the road and my cruise control light came on. I figured voltage had to be bleeding to the cruise control indicator somehow. If it could bleed to there, who knows where else it might go (like to my TPS or at least to that...

Hoping to find a few things locally for my '98 XJ if possible. Here's what I'm looking for:
Roof Rack. Surco, Garvin, Defender... or something decent with mounting hardware. Prefer something long, but not too picky.
Front Bumper. Prefer Pre-Runner style. JCR or similar.
Rear...
Turned out to be a bad clock spring... disconnected the horn relay and all problems are completely gone. Can you believe it?? Thanks for all of the input guys!
Did a master reset on the ECM and then borrowed my friends TCM. CEL codes 122 (TPS low voltage) and 1694 are no longer coming up... as of yet. The vehicle is running much better at the moment. The only symptom I have right now is high idle on start up. Revs to about 2K and then drops down to...
Thanks for the information on the grounds. It does indeed have a ground from the battery to the body, and I am going to run a new ground from the back of the head to the body. It's a little oily (not much), but I don't care for the mesh (aluminum maybe??) ground that is there.
All of the PCMs...
I agree that it sounds more like electrical as well. I am going to try to check your suggestions today. I know where some of the obvious grounds are, but are there any elusive ones that you know of?
Good thoughts... thank you. The fast idle is indeed changing with warm-up... but in the wrong direction. It actually gets faster! I will check the "new" PCM in my friends XJ as soon as I can. I actually sold the XJ to him last week because he needed a reliable DD and this "new" XJ is an...
I have a 1998 XJ Classic, 4.0, AW4, federal emissions, 108K miles that I just recently purchased. It was idling very high at about 2K RPM or more in park and 1.5K or so in gear when I purchased it. My thoughts were that it might have a bad TPS sensor or IAC valve. I replaced both of these...
Maybe there is a slight physical problem with my throttle body itself. I will check to see if my plate is actually closing all of the way. My TPS would be reading accurately if my plate was slightly open at idle. Maybe it's not opening all the way at WOT either. That would sure explain a...
I changed out my TCM to deal with the 1694 code after some research indicated a bad TCM. My 1694 code is now gone. Swapped out the PCM with one that I have in a 1999 XJ, 4.0, AW4. This made a world of difference. It's running very well now and Code 122 (TPS low volatage) is now gone, but I...
I have a 1998 XJ, 4.0, AW4 with 108K miles that is having an odd high idle problem. CEL codes thrown are 122,123,1694. I have searched previous posts and have changed my IAC valve (cleaned port too) and TPS. I have checked for vacuum leaks with a non-ignited propane torch. My TPS signal...
Happy New Year to you as well and thanks for the welcome! I completely agree that if you are running good an quiet that you don't need magic additives. For me, MMO has always been used to keep things going smoothly. I have a 200K BTU wood furnace in my basement and apply a couple of drops of MMO...
I sub a quart of MMO at every oil change and use Mobil 1 full synthetic on my '99 XJ, 4.0. 142K miles... It has been a great combination. No leaks, great oil pressure and best of all, no noises. I also add 6 oz. of MMO to every fuel fill up and have been always been happy with the way she...
