MIKE, 1st see my unique profile.
I'm a CJ guy, I only work on these "cyber" vehicles for my family and friends, I'm a "REAL JEEP" fanatic.I don't usually jump in, and give an answer on something unless I think it might help you get a faster fix. Some don't get an answer, others get one too late! I'm just trying to help, my profile will help you the MOST! ! !
This may help.....Just a member here like you. Unpaid, Hobby right now, Injured at work 15 months ago, recovering now, ready to go back soon!....See my profile. I answer only what I am familiar with.
Written/experienced by me and sent to several other people w/ similar situations at this site........pasting
Our Escape would idle low, then it got to point it would die when you stopped. Reving + holding brake was only way to keep it running.
Took it to fellow R/C airplane pilot, he doubles as a S.C. State HWY DEPT mechanic.
When I got to his house , he was repairing a tractor. Told him my sob story. Escape was still barely running, I raised the hood.
He said,(and I quote).............."It could be the IDLE AIR CONTROL (IAC)", as he pointed to it, and emphasied it with a sharp rap using the wrench in his hand.
It straightened right up, and ran damn good!
That was a 15/16 Craftsman wrench, box end, kinda a medium rap.
YES, I visited parts store and replaced it.
Hope this helps
This, IAC, is sorta a bypass for air to get into your engine, when the "main butterfly" (throttle plate) is closed.
It is strictly opened in certain, fluctuating amounts, by the COMPUTER, to allow in only enough air for precision IDLING
Buddy also said I could clean it.
Took no chances, its WIFEs rig......I did replace it.
IT WAS VERY EZ TO REMOVE/ REPLACE
SIMPLE INSIDE......he said clean moving parts leave motor alone might pay to clean it and try it, VERIFY IAC is problem.
Clean it, just to see if it IS your problem.......Replace it, or go with the cleaning...... If you are certain this is your evil part...Up to you.
This may not be your problem, it was for our Ford Escape. Your rig is using same technology.
Saw you had no replies yet, I know the "Deal" when your Jeep is off-line, for any period of time.
A manual will aid you alot, now and later, about $30 at major auto parts store. ---Really--- read thru it, even if you have no repair to make. Lots of eye-opening stuff in there!
I answered you here, to at least give you something to go on, maybe EZ fix for you!
Hope I helped, send back results.
