So, I was going for a drive tonight in a pretty hilly area and I noticed the Jeep behaving a little oddly.
I was driving down a hill, and I let off the gas completely because I was speeding and then I noticed the RPMs immediate drop to 1,000... almost like I had touched the brake pedal. Then, the RPMs slowly climbed back up to 1,500 (the speed at which the RPMs climbed back up seemed to be dependent on wheel speed) and then as soon as they hit 1,500 the RPMs immediately dropped back down to 1,000. Not a slow drop at all. Dropped like a rock.
1996 4.0. 2wd. AW4 of course.

I just picked up the fan controllers last night and it has a wiring diagram shows power wires going to the battery and the ignition, the ignition power wire turns the controller on and the fans are powered from the battery through its on board relay. So i guess thats the way im gonna run it. also about the tstat, ive been runming a 180 for while now is their really any benefit to running a 190? Ive heard the only reason they had it set that high from the factory is to lower emissions and where I live that is not a concern

emissions are part of the reason, but realistically the entire system is designed around running in the 195-215 range. Other people who install 180 thermostats don't have any issues but I don't see what the point is. Seems like you're screwing with it for no reason.

I've owned a few vehicles with rear window washers/wipers, but never an XJ. The others I had were set-up with a separate fluid reservoir for the rear. I'm assuming the Cherokee does too but it's not obvious to me where you refill the fluid. I certainly didn't find a fill cap where I expected. Anyone care to answer my stupid question?

If you want, I guess heat soak isn't an issue on '90 like other years.

What exactly were you talking about when you mentioned heat soak? Ive heard of heat soak in regards to the cluch fan but im removing that were you talking about the probes for my controllers getting jeat soaked?

About the tstat I really only got the 180 because I was in a hurry to replace it and went I went to the parts store they said they have two different ones 180 and a 190 so I was thinking cooler is better and just went with it, withouI doing any research, but I have had good results so far.
Nope, anything under the hood. Once the engine gets shut off the cooling system isn't removing heat and fuel stops flowing. All manner of sensors heat up and in extreme cases fuel boils in the lines and injectors. It's prevalent in XJs with the mini cats in the exhaust manifold but if you do a lot of wheeling with a slushbox in 4L in the summer or towing it can be an issue. This is mostly due to a lack of airflow.

Don't bother messing with it if it's working then!

Question/Opinion
Should I take off the moldings along the doors on my 97 sport? Do they serve a "purpose" or they just there to be faded and to start coming off on their own?
