I replaced the spark plugs, wires, fuel filter, checked the vacuum hoses and do not have any engine lights on.
Today I had to pull the battery out to jump a neighbors vehicle, when I replaced the battery (which reset the computer) and drove the truck the miss was gone! It ran like a charm.....until I shut it off at the mall. When I started it up again the miss was back! Is my computer bad? Maybe my IAC ??
Any help appreciated!

I am having a similar issue with my 99. this is an informative website http://www.fordfuelinjection.com/?p=13 I bet your pcm is good. my guess is a sensor is bad and the pcm uses a default setting while reprogramming it.
