XJ Ask the Question Thread
If it's a one time deal just pull the steering wheel towards you and whack the shaft with a BFH. Leave the nut on a few threads so you don't end up in the back seat with it, lol.
No, I don't lick fish.

Looks like an Aussie
Another junkyard trick - put the ball end of a ballpein hammer on the center of the stud and put the handle under the top part of the steering wheel. While pulling the handle toward you, hit the face of the ballpein with another hammer - may take a couple of good whacks, but it will come off... guy in the junkyard showed me that trick when I found a leather-wrapped steering wheel in the junkyard in mint condition that I HAD to have but didn't have my puller with me. Just be careful not to pull up too hard on the handle end or you'll bend the steering wheel.

Yes, that's all it does. There's a sensor connected to the throttle shaft (TPS) to tell how far you've opened it, and an air pressure sensor in the manifold (MAP) that approximates the amount of air flowing into the engine.
This is commonly caused by either a stuck Idle Air Controller (IAC) or bad TPS.
When the throttle plate is shut, a small plunger to the right (closer to the engine) is actuated to allow enough air into the engine to idle. This plunger is exposed to oil vapours from the CCV system and can get gunked up, and not move properly. First step to solving this is to take apart your throttle body and clean things. You can find writeups on here of how that works.

I cleaned my throttle body and IAC (iac wasn't too bad but clean now) and then seafoamed through the throttle body. still having this issue. (hot/cold weather / engine , start with pedal)
I'm going to test the tps with my digital multimeter then that passes I'm going to get a fuel pressure test kit and start isolating. I don't want to waste a bunch more money trying to fix my dealership easter egg hunt.
Since you'll have your meter out might as well test the IAC.
Pin sequence;
A B C D
A to D/B to A = 40 to 80 ohms
B to C/C to D = open

I hope I am in the right place on the forum for this. I saw the "Ask a question thread" and read the sticky. So here it is, and thank you for this forum, I have gleaned some great info from here, happy to finally be registered!
I had to remove my AC compressor and now my auxiliary fan does not come on. I thought that it comes on if you either turn on the AC or when the temp reaches 190. If my aux fan is indeed now useless without a compressor (installed dummy wheel) Is there away to re-wire it so i can use the fan?
My 1997 cherokee sport 4.0 now runs hotter than it used to, and the only change I made was yanking out the AC compressor.
Thanks again and i hope I posted correctly.

BTW- i did a search and didn't find anything that answers this question so i came here. Should i have just started a new three in the OEM tech thread?? I know starting new threads can be frowned upon so i thought this was the best place to go.
Thread should be fine here.
Auxilary fan comes on when a/c is on or when temp reaches around 218 degrees. 190 is below the recommended 195 degree thermostat. Still,I'm not sure that without the compressor if the aux fan will still work.
Running hot since you removed the a/c. Before all was good in all circumstances? Possible the belt you used to by pass the compressor isn't tight?

Thanks for the reply! the belt is tightened properly and yes, all was good prior to removal of the compressor. It never ran over 210 even in hot weather and when off road. I will take her for a spin and get it hotter and see if it kicks on around 218. I guess I found in correct info on the 190. Thanks for the heads up. Will post the results when I get back!

Once I feather the pedal maybe up to 30 seconds it will run fine. stable idle when stopping.

^^^ good stuff. Which model years is that good for?

No reason to suspect fuel pressure from your description. How exactly does this thing not start if you don't have the pedal down? Does it not start at all like it can't get air or will it fire and then die super quickly if you don't hold the pedal down? The latter generally indicates a poor battery.

I have tried to search this forum for several weeks about leaks when it rains. i have a 2001 Cherokee sport and took apart the rear & can not pin point where my leak is coming from. 1st I replaced the liftgate weatherseal, but I can still trace a small amount of water coming in the rear driver's side cargo area pillar dripping. This continues to drip thus seeping the carpet in the cargo area then collecting under the rear seat behind the driver. I have resealed the roof rack holes. I have also attempted to reseal the liftgate hinge on that side with silicone. I cant see or feel any water where the wires come into the rear from the liftgate. Please help? I put everything back so my daughter can use the Jeep & stuffed a few rags to collect the water at that one spot to collect the water instead of it travelling thru the cargo area then to the back seat. Thanks

It is running between the first and second hash mark over 210. Are those 15 degree increments? when i do the math to the 260 mark it comes out 12.2 degrees per hash mark...??
Before pulling out the AC compressor it always ran between 190 and 210 maybe if i was in 4WD going slow on a trail in the desert it would climb to just above 210 but never higher.
