Hi:
First, there is no easy way to get to the plugs. You just have to work your way to them. Also, yes, a fouled plug will cause a miss, but so will a clogged injector.
What I suggest is to stop at a nationally recognized parts store and have the computer scanned for codes. Let me know what they find. Also, if the plugs haven't been changed for awhile, it can't hurt, and it would be a cheap fix if it works.
Let me know what you find, and just FYI, most of the parts stores will scan the truck for free.
