Okay I've had this problem for quite some time now and I'm tired of it.

Jeep will run at normal temp finally with a new aluminum radiator. But if I shut it off sometimes I have to wait for it to cool down even more until I can restart it... any ideas???

 

keep light and the skinny pedal when it feels like it's binding and you should be fine. I have no issues with mine and I'm Rollin 32s. just be aware of what you are doing.

 

Any ideas as to where this would plug into? 88 cherokee base model

 

You're having problems with heat soak. There was a recall on this for certain years (check the NHTSA website), and they corrected it with a piece of heat shielding on the intake to insulate the injectors. Hood vents would also help by reducing the temperature under the hood.

 

I feel like there should be a picture, but I don't see one

 

One of the best set ups I ever had was 31 inch tires on the factory wheels, 4 inch lift and just a few mods for longer brake lines, sway bar discos etc. really no big spend. Made an awesome trail runner like you described. The first pic is just 31 inch tires and a mixed parts lift. Old model rustys steering, coils and a leaf pack. Second pic is getting a bit bigger, shackles, sye, arb bar, locker etc. I guess I'm really getting old since these are actual photos!

 

there ya go I fixed it

 

Much better! I don't know off the top of my head, but cruiser54 probably has an answer. He's our resident Renix ('87-90) expert.

 

Should never have that problem since it has the Selec-Trac NP242 with the full time option.


Came with stock size 225/70r15 and I only plan on upgrading to 235/75r15.

 

Based on shape and general vicinity, I'd say something that attaches to the throttle body. Map, or IAC maybe? Just a guess though. Like Clown said though, Cruiser might have a better idea for renix.

 

Yup.

Your 88 had the factory CPS bypass harness installation and the mechanic didn't snip that plug off and tape the harness back as the instructions said.

 

I almost want to say that's the Engine Speed Sensor (better known to us as the CPS) plug. My FSM for '87 shows Violet w/trace and White w/trace wires go to the ESS (CPS).

So... does the Jeep run? And are the wires the colors I think they are?

 

Cruiser, you beat me by a minute cause I had to break out the books

Details about this CPS bypass?

 

TSB where you installed a CPS with a SLOTTED upper hole. Imagine that.

Drilled a hole in the firewall and ran the harness through the hole and to the ECU. Remove the original CPS wires at the ECU and run the patch harness wires into the ECU connector instead.

 

Interesting. My '88 Comanche definitely didn't have that service performed cause I clearly remember the process of replacing its CPS. That's good to know, though. I was hesitating and kept rechecking my diagrams cause I felt like if I was right, he would've complained of a no-start situation.
