Missing when engine reaches operating temp

I have a 94 f150 with the 300 six. It runs fine when it first starts up but when it reaches operating temp it starts missing so bad it can't be driven. Could this be the coil?

How long since it had a tune-up? Plugs, wires, fuel filter? Have you checked for any error codes? You can find out how to do that at fordfuelinjection.com

Don't think it would be the coil. If you had a multimeter you could ohm the coil cold first then ohm again when its running crappy.

Pull some plugs and see what color they are. Should be a tan color. It might tell if it is a fuel problem.
