I have found that the IAC is closed when warmed up. Is this correct? As long as it's open it idles and it's open until it reaches operating temp. If it's closed and butterfly is closed how could it get air? Thanks for your help.

Just a little more info, switch throttle body from a running engine and still does the exact same thing. I left all electrical on new throttle body. Will idle when cold but once warmed up won't idle

Cruiser, hoses are correct. I've owned it for about three years.

1988 4.0 automatic had a fast idle, I found a rotted rubber vacuum line and replaced it. Now it will not idle with all vacuum lines on where they are supposed to be and no vacuum leaks. Can remove a line and idle comes back but is too fast. Thoughts?

And it is ribbed.

Looking for the lower body side molding that is about 5" wide. Need all the pieces for a long bed, any color.

Going from 2wd to 4wd requires moving transmission as well as case.

So it would be ok to use the 88 TCU with the 91 tranny?

Converting a 1988 2wd automatic Comanche to 4wd using parts from a 1991 xj. Question is which TCU should I use? Will the 91 TCU plug into the 88 harness? Thanks for any info!

Got another one. Pictures will follow on both shortly. Thanks

Need help with this VIN, pictures coming. Thanks!

NHQ transmission heater? Has a 44 rear, is that original? Pioneer edition with Olympic package but nothing about that in the build sheet. Thanks for the help!

Olympic edition

Thanks for the list. So is this a factory Eliminator? And originally black? Thanks again!
