    My 1994 f-150 in-line 4.9 starts and runs great but regularly appears to misfire. I can get it to run good again when I rapidly switch the ignition key on and off. This works well for a while but the issue keeps coming back. It seems to happen more when the air temperature is warmer. I hope someone might have some good ideas.
    Thanks

    Does it quit? Any check engine light? So many possibilities that can be causing your issue. Have you done anything to it yet?
