it says that the idle control valve is hard to test because it is a stepper motor and the ecu just tells it to open/close at a super high rate. it says the ecu won't even know if you icv is bad because it gets no info from the part and keeps trying to adjust the idle even when the icv is bad...

if you can find a download of the factory service manual, it will give good instructions for how to check that stuff. i probably have a cd version of the 87 cherokee manual somewhere but i know i will forget to look for it when i get home. i did find this though, on another forum "The...

Is the other the throttle position sensor? Its been a while since i had my renix cherokee. The good thing about the old renix fuel injection in your jeep is its very easy to trouble shoot using just a multimeter.

maybe your idle control valve is no good anymore? the pump holding pressure, do you mean its not putting out the required pressure for running or it bleeds down after you shut the truck off? if it bleeds down after shutting off, that won't effect the running issue but you can buy little...

your idle control valve And its area of the throttle body are clean?

holy crap!! that is bad luck

Ok. Good info

To get rid of fuel injection, you can remove everything but you might need to get a different distributor. You need to find out if your current distributor has vacuum or weight centrifugal advance or if its electronically controlled by the ecu. If its controlled by the ecu, you have to see if...

I haven't done a 4.0 but i have done a few vehicles. For you, an offenhauser intake for a 4.2 and holley 390cfm four barrel will work great. Thats what i out on my 87 wrangler and the gas mileage and power improved unbelievably. I tried the motorcraft two barrels everyone loves but the 390...

i found an article on the 2wd wrangler but i don't think its 100% correct. it says only 2wd was available from 2007-2010. https://www.autotrader.com/car-news/jeep-once-sold-two-wheel-drive-wrangler-and-it-was-weird-281474979998290 maybe they say that because it was available at the...

i bet the heat is what is doing it also

that is how ours have been. my wife loves wranglers but she doesn't do anything in it that it is made for. she uses it like a civic or mini van. her old 07 jku was the best wrangler for her, ever. it was 2wd, ha ha ha. she didn't even know it wasn't 4wd nor ever noticed the transfer case...

i have a question guys, do soft tops need to be treated any differently when you are in the snow? not so much the vinyl black part but the windows? do i need to be particularly careful when its very cold or the windows will split or crack? we have had lots of wranglers over the years, i...

the newest model, the jl, is very very nice compared to past jeeps. the interior is so much more refined than even the jk model. and the 2.0 with e-torque is awesome. my wife has the jl unlimited (jlu) which is the 4 door and its a 2019 model with the 2.0 turbo motor and e-torque (has a small...

Welcome!!

No idea from me

i have found the best way to loosen stuff like that is with the longest breaker bar i can find so i can apply smooth easy torque. turn it a little and then turn it back the other direction to clear the threads. than turn it some more and go backwards to clear the threads. just keep doing it...

there is no easy way to find out what came in it. jeep has changed owners so much that no one kept the records, it always seemed to me when trying to find info. it would probably be better to take a picture of whats in the engine bay and what transmissions/t-case is on it. tons of people...

thats a lot of metal to remove. google has not been anble to answer that for you? i have never heard of anyone going up that much
