Followup: I started the jeep and pulled the IAC wire off while it was running. The jeep stalled and then I reconnected it and cleared the codes. When I started it back up the idle was back to normal. It had to be something with the IAC but when I look at my manual the 04 libby has the IAC incased somehow in the throttle body and not connected by two screws like the manual says. Anyone familiar with how to take off the IAC on an 04?

I tried to reseat the TPS and that didn't do any good so I replaced the TPS. Took it for a 10 mile roundtrip ride and didn't get any codes or pendings but the idle is high. In park, hot engine, it reads 900 then will jump up to 1100 then go right back down to 900. It will keep doing that.

Could it be the IAC (idle air control) ?

Any help would be appreciated.

Thanks,
Jake
