You may have damaged the IAC, and likely disturbed the coated surface of the throttle body. Unless you have access to a bi-directional scanner and can check the operation of the IAC, I'd replace the IAC.
... When a Ford technician has a problem with a dirty throttle body with a car under warranty, he must either clean it without getting paid for it (and not documenting that he cleaned it as well) or replace it. ...Truly though, the teflon does help, but it doesn't eliminate the need.

If you are "lucky" (or unlucky depending on how you look at it), after the warranty is over, they will suggest to clean it for $127.
