It is VERY common for them to develop cracks in them and cause the engine to miss. Wall's Expo did it and a guy we work with had a problem on his f150 because of it. I think Wall researched it when his was going out on the Expo and saw that it was very common on the 5.4's for some reason. Occurs around 60k-70k miles.
