IAC stays extended when cold
#11
Lets start over
First how do you know its extended 100%
Second Im guessing you mean a 3.9 not a 3.7
#3 have you rebuilt it or cleaned out the throttle body these usually need a good cleaning?
#4 the IAC units usually don't go bad my guess the TPS is bad they go bad all the time or the throttle body is gummed up.
My TPS has needed replaced many times for Idle problems oem or quality is needed for a TPS.

Hey guys. Thanks for all the good advise. Unfortunately I ran out of time and had to work out of town. My girl needed the truck so I put it in the shop. They said they scanned the system, test-reset and relearn IAC System, cleaned the housing and replaced the air filter.
So far so good.Sounds like you guys where right on about the relearn. I will know for next time.
Thanks again!
