Clean and tighten your battery terminals first. A dirty connection does that.

 

Been looking at the AUX fan override methods lately, why couldn't you use a DPDT On-On-On style switch and a dummy load(1kOhm resister) to prevent a CEL in the later year XJs, similar to the AW4 mods? Then you have On, Off and PCM control with one switch and a couple resisters rather than hooking up a relay and associated wiring. What is the PCM checking to determine the CEL?

So last night I installed some LED lights on my trunk hatch. I was trying to tie them in with the cargo dome light. There are 3 wires. Pink, purple, and yellow. From what I read, pink is constant hot, purple is constant ground with hatch, and yellow is constant ground with doors. So I spliced into the pink and purple wires. Now when I open the hatch, the led's come on, which is great. They go off when the hatch closes. Great. But when I try to turn them off by pressing the cargo dome light, they just stay on. I was hoping I could use the dome light to turn them off and on. How would I do this? Should I have tapped into the doors open ground?

 

Sounds like a good idea. Give it a shot!

 

i would like to ask what is the best oil weight to use in the summer for a xj 94 with io6 only has 155k on it but oil pressure drops to 10 once warm and just put new 10w-30 in help please

 

my oil pressure droped to 15 psi so i changed oil with 10w-30 . not sure if correct weight but it runs 40 psi going down road and 15 on idle unless real hot outside live in florida so what is the correct oil weight for 94 xj quad track

 

10w30 is fine.

So does your oil pressure drop to 10 or 15??

 

Make sure your terminals aren't ripped on the bottom:



Mine started doing what you're describing and it ended up being that the soft lead just literally tore apart.

 

It hit me like a tonne of bricks in the shower this morning why the petrol / lpg tanks are so badly rusted along with the rear exhaust section, brakes and rear suspension. The guy I bought this off let it stand for about 4 years after he bought it. However, the guy before him had a small boat he used to trailer around. He must have been backing the trailer in to the water and submerging the rear of the car with it...

 

That would certainly do it! Here the spray from the road brine is worse around the rear axle.

 

we just bought a 93 jeep cherokee my son owns a 98-99 jeep cherokee is there any issues with the distributer to change it only to get the motor to run were putting the motor tranny and transfer case for now in the 93 body wondering if we need to change anything or can we just remove everything from the 99 to the 93 without much difficulties let me know if were going to need to change other stuff we hear we might need a 93 distributer this is for the 99 4.0 drivetrain going into the 93 body please let me know

 

You might get some help if you make that post coherent

 

x2!!

Posts that are hard to read and understand i usually just skip over.

 

That is one long sentence!

 

Having a little idle issue. When sitting still at temp and idling my RPMs with drop and spike about 250, the jeep will lurch and act like it'll die for a split second when the rpms go down. Cleaned out the throttle body (some carbon build-up), checked the air filter (clean), and sprayed some sensor cleaner into the MAF sensor. Stopped for about a day and had a 30 sec to a minute fit earlier tonight. Could the injectors be causing this? The gas stations just changed out their winter mixture to summer mixture gasoline. I'm not sure what could be causing this.
