the 2005s had a problem with the factory TB...the plastic compound shrinks too much in the cold, and it causes the plate to stick. cleaning will help, but when it gets really cold, like below freezing, it will become a bigger problem.
Ford issued a TSB on this, not sure if it reached the recall level, but when i brought mine in, they swapped in a new tb right away, no cost, and no questions. the new ones had a stronger/thicker wall so they did not constrict like the originals.
