If your engine fouls a plug, the plug will not fire. When that happens, you will detect a "miss". That "miss" will also manifest itself as a shuddering when you accelerate. At that point, you'll then have to determine WHICH plug isn't firing. There are several ways to do that, but pulling the plug wire off of a running engine, one wire at a time, is NOT the way to find it.....unless you're seriously short of your senses. I don't mean to make light of the situation, but there have been some instances when people just didn't know what they were doing.......

Like, peeing on the sparkplugs of a running flathead Ford, while standing on the fender, barefooted....

If you are driving 15 miles/day, you should be able to easily tell if the truck is running right, or not.

I had a '65 Chevy, running a '71 GMC 350, that gas-fouled the plugs very, very often. Trust me on this one, you'll know.....
