Welcome to the forum. The IAC motor is located in the top of the throttle body. It is held in by 2 star-screws. Remove them, remove the IAC motor, clean the spindle end with throttle body cleaner, and clean the entire throttle body / throttle plate itself. If it was infact, IAC motor/TB related, a thorough cleaning of both with TB cleaner should fix it. If it's dirty enough, you'll probably have to flush the cavity in the TB several times with the cleaner, and go over the rubber / spring on the motor several times.
