    It could be a wire arcing, distributor cap or coil.:confused:

    Open the hood at night with the lights off and hold the break on and with it in drive and put a load on the engine like you would a break stand. Remember to hold the break hard. and have someone look at the engine wires and distributor for flashing/aching. If you don't see any sparks repeat with 1 plug wire off at a time and see what one makes a difference to find what cylinder.

    No sure , but there have been many problems with the sparkplugs-- threads wiping totally out-- don't know if it's your year engine or not.-- may want to do a search for threads! I hope this isn't you problem best of luck!

    the spark plug may have blown out of the head. More then likely you have a spark jumping to ground and not firing the plug.

    The new 5.4 do not have plug wires they have coil packs on each spark plug. You may have a bad coil or a plug blew out of the head.You will have to take each coil pack of one at a time and see if you can find the plug or take one off and start the engine and see with one is not firing. Steve
