Whats wong with the plugs going to your coils? If the wires are messed up thats one thing but if its just the clip there are ways to hold the plug on.

Coil plugs are not like spark plug wires they dont rly go bad like mentioned above did you scan the truck? what cylinder is missfiring? 4.7s are known to missfire for many reasons coil,plugs,rocker arm fell off,timing jump if the guides where never done ect would be a good idea to run a compression check to.

they may not be the problem, just replacing them along with other parts.
