Bad plugs, wire , or coil pack.
Could be a bad ignition coil each cylinder has its own
I had the same problem with a 1999 Expedition and it was a bad plug. Ford had a problem also with the plugs blowing out. It cost me about 1200.00
This could be caused by bad wiring but is usually caused by a weak coil. Change the plugs and install a new coil....I'd recommend doing all of them. This should take care of the misfire.
