I own a 2004 F250 V10, just had the plugs changed this week, I have 72,000 miles on it and a week or so ago it was very damp and rainy and I had a miss, so I put it in the shop to check plugs and the sparkheads on each cylinder. The shop suggested changing the plugs but all the sparkheads checked fine. I previously owned a 1997 F150 with the 5.4, drove it over 100,000 and no problems with it spitting out plugs either.
A miss is a common problem when reusing the plug boots. I reused mine and had a miss even though they looked good. I tried to save a few bucks and skipped on doing the boots. When I retorqued the plugs i replaced the boots and the miss went away.
