This is caused because the ignition timing is retarded on start up in order to heat up the emissions components. It is retarded as much as 9 degrees. Perfectly normal, its just fords way of getting their trucks to pass EPA standards. In all my cars I always let them idle down before moving. If I don't do this in my mustang it will drive itself.
Seriously though thanks for the info. I'm glad to know it's nothing to worry about.
