Buckle the seatbelt
Pull the PCM fuse
Turn the key to the on position
Wait for the 3 chimes then turn to off
Put the fuse back in and it is now reset.
Easier way, and keeps all your radio settings and whatnot! Also, I believe resetting the PCM re-zeroes the IAC and TPS anyhow.

So here's an interesting twist!
Haven't had a chance to look at the throttle body yet but the check engine light came back on with the EVAP codes. But now the truck doesn't die at idle. Would it make sense to assume there is a hose/vacuum issue somewhere that the computer is compensating for? Guess I need to take it in to get a smoke test because I can't find any other holes. Any other thoughts?
Not sure if this is relevant, but the truck was dying at idle when the engine was still cold. Once the engine got going it was ok.

PO440. But I replaced the gas cap three weeks ago so it shouldn't be that.
