5.4 misfire
Time to get the misfire counters read at a good auto shop
How many miles on this 5.4?
Have you changed plugs yet ? and boots?
Have you looked for water in the sparkplug holes?
Yes as stated cop's do fail on these engines.

Coil on Plug
The design of the modular 5.4 has a coil for every sparkplug it actually sits on top of it. No sparkplug wires anymore.Under the coil is a boot thta protects the spring connection to the plug and will prevent moisture from shorting out the plug .
But because of heat build up .The coils go bad and the boots burn up.
