I have a 1988 Cherokee Laredo Jeep (4.0 automatic). The idle surges and then gets stuck around 1500 RPMs/2000 RPMs and stays there while driving. My Jeep will drive itself. This morning I cleaned out the throttle body, linkage, carbon out of the idle air control motor and cleaned off the throttle position sensor. Then I took it for a drive and it did not change the performance. I am a single woman whose learned how to work on her own Jeep. I am so frustrated. My Jeep will not idle properly at a stop light/sign and when I come to a stop I fight the gas and the brake. Please help me!!!

Thank you for your response regarding my Jeep. I even went and replaced my sensor and idle speed control motor and my jeep did not respond. Just the other day I crawled under my Jeep and notice how much oil and dirt was up around my transmission and I notice some linkage I missed cleaning. I cleaned that linkage around the transmission and the idle came back to normal. I can't believe I had this problem for nearly a year. I did a tune up and my Jeep sounds good and responds well. I think it had to do with this heavy corroded dirt preventing shifting/sticking.
Peace be with you, Jewel

It's those things that you really wouldn't think of that get you... On my buddy's Mustang, it was doing the same thing, he was thinking vacuum leak, broken cable, all kinds of things, it would want to fly down the road at red lights... A little WD40 around the throttle body where the cable moved, problem totally solved... Glad you got your Jeep up and running properly, and welcome to Jeepz, hope you stick around.
