Could the oxygen sensor be bad, damaged, not fitted correctly? I'm unsure if they could cause the misfires. Have you checked your plugs? Welcome by the way, enjoy forum, hope this issue gets sorted out.

Have you hooked up an obd2 device to see what codes are there?

Yes there are none 

 

If the engine is misfiring that should be shown at least. Apparently there is a windows app called forscan that can be used with for cars, they use a specific Elm connector to work, and this particular diagnostic program will show many a thing a simple obd scanner will not, and it is very ford friendly. The program is free to download but unfortunately the connector isn't although it is fairly inexpensive. I have provided a link to the scanner if you are interested.
