it does it all the time and when you are driving it also goes up higher and you have to tap the gas pedal to bring the idle back down.

    Release the accelerator cable to make sure it is allowing the throttle butterfly to close fully in the throttle housing, after that I would be looking for a vacuum leak.Also make sure the throttle shaft is not badly worn.
