idle problem
#1
Hi I have an 04 Cherokee with the Inline 6 and when im setting at idle while in drive my rpms surge a lot. Its not real noticeable on the gauge but I can really notice it physically and hear it.
Ive also have cleaned out the throttle and idle air valve with no luck. Kinda seems like a vacuum leak but cant pin that either. It only does it in drive and at a complete stop.

Sorry im brand new to the forum. I posted in my initial thread that I did clean the throttle and iac. I have also done a tune up just before winter. I will try the tps sensor though.

Do you happen to have the A/C or defrost on when this is going on? If so, it's normal for the RPM to fluctuate when the A/C compressor kicks on, or when an electric cooling fan is switched on.

Okay I found my problem and I fix it. Changed out the idle air sensor the TPS sensor and the map sensor with no luck of fixing my problem. After changing those out 2 days later I got a check engine light. The trouble code said that it was a pressure control solenoid in the transmission. So I begin to investigate symptoms of that solenoid and it was exactly the same as what I was having issues with. So I went ahead and changed it and I found a kit from a website called cascade transmissions that had all the exact replacement parts. It came with the solenoid and 2 other sensors a 3-4 shift spring ( which mine was broken ) along with the kit to replace the transmission filter($150 vs $198 for just the solenoid from Jeep). After doing this all the problems I was having was gone I've been driving it for 2 weeks since I replace everything and have had no problems. My Jeep gets better gas mileage now and drives a lot smoother no idle issues whatsoever.
Also found out same symptoms I was having can be caused by a stretched shift linkage and low transmission fluid.
