problem

I have a 2004 F150 that when I have the a/c on and come to a stop at a red light the rpms drop real low and has sometimes cut off. What are your suggestions?

I would look at the IAC which controls what happens when the truck is at Idle. Usually you can clean it by taking it off and soaking in WD40 and a small brush

What he said. Might have to take it to Ford for a re-flash. Or get a programmer and up the idle with it...

I have the same issue with my truck which also displays a yellow check enging icon on the dash. What and where is an IAC and how difficult is it to conquer? BTW, great forum, lots of good stuff.
