If you switched the coils to the opposite side and the codes stayed on the same side, you can be sure the problem is on that side. Was there any water in the holes where the coil boots connect to the spark plugs?

You have a f250 but on my f150 as of last week started to do the samething. My truck has been at ford since. The found 1 fuel injector leaking and they can figure out what is causing the other 3 misfires. They are suppose to take it for a drive today while a tech is in the pass seat running test.
Anyways, might be your injectors.
