There is something wrong here. I'm not sure of the code, but the 5.0L doesn't have a IAT sensor it has a engine colant temp sensor. Now the 4.6L engine does have a IAT. So am thinking you got a 4.6L, and if it goes bad it will cause those semtoms.

Autozone has this website that has limited use, but good info when its there. check out:
