Default 2006 Won't idle when warm.

I have a 2006 Limited. Only had it for about 6 months and have had nothing but problems out of it. The current problem is it won't idle when warm. Just did spark plugs yesterday. It threw an error code of 113 I checked the IAT sensor and it seems that some of the wires might be compromised. It's not giving me any codes now though. Will this keep it from idling when it warms up? It runs fine when cold. Any ideas?

Welcome to the forum.

P0113 - IAT Sensor Circuit High Input:

Possible Causes:

IAT Sensor signal circuit shorted to VREF 5 volts
IAT Sensor signal circuit is open, or the ground circuit is open
IAT Sensor is damaged or it has failed
PCM has failed

P0113 can also be caused by a vacuum leak. Check all vacuum hoses. Check to make sure your PCV valve hose is not cracked or leaking and your PCV valve is working properly.

Welcome to the Forum
Check the wiring harness ground to left fender ground behind the battery
I've have problems with the grounds oxidizing and breaking at the grounding lug.
Looking at it will not suffice.
Good luck
