This morning on my way to work I decide to stop at the Self Service car wash (power-wash wands) and clean up my baby because she is dirty. It seems a little cold but other people are washing their vehicles and I don't think much of it. Come to find out it was about 28F degrees (shouldn't have washed the truck being that cold). Long story short...The engine starts fine and idles fine (maybe a little low) but as soon as I put it in gear (auto trans) it dies. I have tried revving the RPM's up before I put it in gear and that doesn't help, it still dies. The service engine light also came on. I had to have a friend (light duty F250) tow me home. How embarrassing. I ASSume that I caused this by washing the truck when it was too cold because it happened pulling out of the car wash. But I'm afraid it is not as simple as something thawing out and everything works great again. Bottom line is even after letting the engine run for 1/2 hour whenever I put it in gear (drive, reverse, whatever) it dies. I probably broke something (a sensor maybe?) Any ideas???

Dumb A$$
You didn't spray the engine compartment though, did you? A friend's 1998 F150 4x4 auto did that about 3 weeks ago. I told him to go get a new IAC and it fixed it.
Spraying the grill won't harm it. It was probably just a coincidence. If you can get the code pulled, the IAC will set a P1504 if its bad. (My friends F150 had a bad IAC but no codes.)
Have you done any modifications to the air filter housing? The throat of the housing extends to the front of the truck. If you got any water inside that housing (it usually takes quite a bit, though) then it may be getting past the filter (gasket) and accumulating on the MAF sensor. Every time your PCM detects it going into gear it may be getting a signal from the MAF sensor telling it that there's too much moisture to run.
