Irradic idle
My 04 4.0 has a high idle at start up(1500rpm) for approx 2 min then comes down to 7-800.
After driving with the cruse on far say 30 mile or so. Then i can turn it off, push in the clutch and let off the gas completly(coasting) the rpms sit at 2000-2200. Driving thru town i can be crusing in 2nd at approx 1500rpm and go to shift to 3dr, but when i puch in the clutch and let off the gas, the rps come up to 2000. I have check mutiple times for vaccume leaks and found NOTHING!! I have put in a NEW TPS, IAC and a PCV(if yoou want to call it that). Still has the same issues. It is very annoying for the past 10k. O and the throttle cable is free as welll as the Throttle body Please help

Re: Irradic idle
Ok. i changed out the IAC and it did nothing. I have driven it this way for the past 20k. Finnaly got sick of it and droped it off at the shop by my house. Guy said he reset the computer(have to after changing IAC?) now it idles fine. And he charged me 2,5 hours do do that
