Truck is stalling out in cold weather.

Truck is stalling out in cold weather.
I recently purchased a 2001 5.4L F150, and it has been dropping below 500RPMs and stalling out everytime I start it up in cold weather; the only way I can keep it from not stalling it out is by giving it some gas, however long it takes to warm it up. Could it be the AIC, or would it be something else?
I was trying to take the AIC out so I can see if it's clogged, but it's in a very awkward spot, I can't really loosen the bolts.

Did the PCM throw a code? If you got a code for the IAC, you'd know almost for sure it was bad.
I've never taken just the IAC off by itself, but it wouldn't hurt to take off the entire manifold and give it a good cleaning. Might not take all that much longer than just taking off the IAC; it is a bitch to get at and having a nice, clean intake will make the truck run better. Either way hope you get your problem solved as easily as possible.

It fouls and sticks, a few good whacks frees it.
I beat on mine for a month because they were on backorder.
That two foot driving with power brakes is for the birds.
