Is there a list of multimeter ranges for other sensors? I plan on testing the IAC CTS TPS and Oil pressure sending unit. Going to retest my fuel pressure according to a post I saw

Maybe too late for this info, but I found a problem with my 4.0, and probably with all 4.0 that have been neglected. You get an accumulation of crud, slim at the back of the block. I've tried vinegar,(don't leave it in too long 4 days max), mean green, ammonia. Next is Oxy Clean. Only way to get to it is remove the trans or motor, and pop that back plug out. You'll be surprised at what you find

DON'T use compression fittings on your brake lines. Most states it is illegal!!
Flare fittings only, for your safety and the other guy.

i used compression fittings on brake lines of different vehicles I owned and never had any problem with them blowing apart or leaking. And I know so many other people who have done the same with no problems.

Question. My JY Driveshaft that i rebuilt for the front, same size as existing rear one (which use to be the front one) has play at the slip yoke, up and down movement. Can i rebuild the slip yoke or just have a Driveline place fix it. Can it be fixed? Didn't notice it as i did the u joints.

I just want to gather opinions on this before I jump the gun. What clutches do you guys run on your 4.0/AX-15 combos? I work at autozone so I can get the duralast with a discount but if there's a better, more commonly trusted one, I'd like to go with that

I used this test on my '96. '91 thru '97 use the same IAC.
IAC ohms test:
Pin sequence;
A B C D
A to D/B to A = 40 to 80 ohms
B to C/C to D = open

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
Tried using a hose (slow running) to find the leak?

So, I replaced the fuel filter today and this thing was dated 05. To my horror when i pulled the end going into the metal fuel line...
THIS CAME OUT
So my question is: What should i do about this? Seafoam for the next 10 tanks? Or just replace my injectors because there's no way those things could be working right

Picture isn't in focus, all I can see is dark stuff and I think a pine needle. Are there particulates in your fuel?
If you're concerned about particulates in your fuel system the only thing you can do to clean injectors is to back-flush them.

The dark stuff is gas. It came out that nasty rust color.

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

Thinks its the latter. Thanks for the help. I know I'm kinda freaking out since there was an attempt on the life of my XJ. Going to see if I can scoop up some 4awg at advance to upgrade.

I tried the perfection kit from advance on mine and within 5000 miles the TO bearing was shot and the friction disc was bald. Second time around I'm running a Luk kit with a full metal Crown TO bearing. Never had a problem since.
