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!

Thanks for the kind words! Anybody got a picture of the correct HO pioneer stripes? I may not have ever seen those.

Are 5.9 springs the same as the ones on a 5.2 Grand Cherokee?

Thanks for all the information! I'll decide which way to go soon. And thanks for the spacers!

Installing an ARB front bumper with 9000 lb. Warn winch on an otherwise stock 91 Comanche and looking for recommendation on front springs and/or shocks to maintain ride height. Thanks!

Cruiser, seems the tube is partially blocked as very little air is getting through. Is it ok to replace it with a piece of vacuum hose? Does the hose need to be a certain diameter to regulate the amount of vacuum? Also Don I'll check the codes and voltage. The check engine light did come on when I removed the line. Thanks to you both!
