With multiple misfires originating from the same coil pack, my guess would be to replace the driver's side coil pack.
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
Could be a bad ignition coil each cylinder has its own

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.
Bad plugs, wire , or coil pack.
Change spark plugs and wires... TUNE-UP...

Plugs or / and Coil Packs. Auto Zone will check your codes for free and will tell you which plugs or coils are bad. Then replace.
Most likely a bad coil (each cylinder has one) located at the top of each spark plug
