How many miles on the plugs? I think ford recommends you change the plugs at 100k. If you actually have more than 50k on them I strongly recommend taking you truck into the dealer. My neighbor tried to do the plugs on his 10' f-150 with the 5.4 and all but one broke off the extended insulator and he had to have it towed in for the job anyway.
