The coil is not seated correct or it has become bad also. These have a tendency to mess up on a regular basis. I use a di-electric grease on mine to help it from misfiring. I would take that #4 back off and re-seat it and see how it performs.

If you haven't tried this yet see if you can find out if there are any Diagnostic Trouble Codes on your Trucks Computer. Auto zone usually does this for free. Ford has had issues with faulty fuel injectors and they are covered under a warranty. Also you may want to see if it is the catalytic converter, it is also under a extended warranty from the mfg as long as it can be proved it is bad. I recently had one of my fuel injectors replaced and later on the catalytic converter. Truck only had 36k on it.

SOURCE: Truck not firing properly front coil pack not firing at all.
if this truck has an o2 sensor i would replace that and also make sure the cat-converter is not plugged,this would give you your powerloss and egr code,next is your coil,this may be caused by the computer or your crank sensor,look at the tone ring that the crank sensor uses and make sure its not missing teeth or broken,also check all your fuses.
