my 1979 ford f100 cuts off while driving at the same time I can push the gas
pedal all the way down it starts running again. I have change these parts
trying to fix it. I rebuilt crab also replaced all spark pugs and wires and coil pus

I did all this it ran for about a week and start doing it again.
