Well, I broke down and went to Ford. I had two bad COP's (cylinder 2 and 3). No check engine light but they were able to find the misfires one at a time by looking in the memory. I actually picked the truck up after they fixed the first one and it still hesitated, so they went back in the memory and found the second fail. No more hesitation!!! Next time I am just going to buy the remaining six COP's and replace them myself, so that they will all be new. For what the dealer charges to diagnose and replace two I can buy the remaining six for anyway.
I had the dealership look at the plugs when they replaced the two bad COP's and they said they looked great. They said the previous owner had already replaced them, not to long ago, so there was no reason to replace them now. I have only owned the truck for 7 thousand miles. Next time I see the old owner I am going to check with him on when they were replaced.
