I have a 92 F150 w/5.0 and an auto. It runs and drives fine, but when it is warm (after a drive down the highway, or within 1/2 hour of a recent drive) it frequently dies when I put it in gear (drive or reverse). I don't have this problem when it is cold. I checked and there are no codes, I didn't see anything obvious looking under the hood. I put a new IAC on it (I was SURE that was the problem) and it acts the exact same (I guess I have a spare now ;-).

The truck is tuned up (good plugs, cap, rotor, wires, etc) and runs good other wise. it has about 120k on it. It has done this since I bought it one month ago. I can drive it, but I just have to time it so that I give it a little gas just as it goes into gear.

Any Ideas?

thanks.

Is this carb or fuel injected?

 

The truck is fuel injected and bone stock.

you can try turning that screw on top of the throttle body to raise the idol a bit, it might help but this is usualy a temp fix to a underlaying problem, spray out your pcv valve also with some cleaner of get a new one. might help.
