I have a 5.4L in a F150 with 90,000 miles on it. It has developed a miss in the engine when under load and at low RPMs right before it shifts down. Dealer changed fuel filter and stuff. They said next thing to do is change the spark plugs, said it's a real pain to do and figure 5 hrs of labor. Any other ideas on what it could be or experiences.
