Well, well, well, the Cow Chick got it right. Just for the record, I knew the solution before posting the problem, it took Hammer all of 4 seconds to figure it out. The problem hadn't occurred around town because I haven't done much in town driving, mostly highway. It's a bad wire, running to the #5 cylinder plug.

Not to toot my own horn, cause even a blind dog has a rabbit run right under his nose once in a while, but I had the same story last night on AIM, that y'all got.
Pyro stated that he thought his TC was going and I asked him the symptoms, then asked him if the tranny was slipping during the surges, because that's what happens when the TC "slips".
I knew at that point that a cylinder was not firing off intermittently (and you won't get a CEL if the cylinder fires off the next time). The truck had to rev higher to maintain speed with seven working cylinders. So a problem within the cylinder (piston, lifter, etc.) was possible, but usually not the case with an intermittent problem. Broke parts as a rule, do not fail, work, fail. Only things do that are damn electical problems. So I told him to get his a$$ outside and check his plugs and wires, figured it was a severely cracked boot...
BTW Pyro, get you a new wire set yet?
