find a nice straight away and cruise at 40mph. if you have to stop and the idle is still high just apply the brakes a bit harder. your not going to peal out or anything at 2k rpm.

 

if that doesnt correct the issue go back and swap out the IAC with another unit. if the problem still accrues, thats when you can start check for other issues, such as wiring, etc..

 

Although you have been "depribed" of the ability to adjust your TPS, (we Renix folks can), you can still check yours. Also, if I could just park at an O'rilies or auto zone and have someone come out and scan my Jeep, free, I might do that. Maybe there is something other than the evap code.....Renix has no intake vacuum lines to the evap can, if yours does that could be a leak/high idle.

 

crazy... my jeep JUST started doing this today as well... going to start checking into it here soon... I have already cleaned the IAC and the throttle body a few months ago..

 

Turns out the part needed to be calibrated. The stem was totally retracted out of the box and needed to be pulled out to 1 1/4" to idle properly. Thanks for all the responses.

 

IaCs can be calibrated
