my 02 does the same exact thing man. i swear. i started it up last night and revved it up and it still almost died. i have an auto and when i put it in reverse it lurched and almost died. it's gotten real bad about this. and my ac was off by the way so it wasn't my compressor. it's really annoying
i think i'm gonna go bug ford about it, i still under warranty. gotta love em
