Very high Idle?

I would make sure there is not a floor mat holding the accelerator pedal down, next there is a large vacuum hose going to the PCV valve which is in the valve cover. If that is okay, I would swap out the IAC motor, here is the location so you can check it out. Also, please go over this guide:

If you have not serviced the throttle body recently I would do so, this guide can help as well:

If you have a check engine light on, please let me know. Check out the images (below). Please let us know what happens.
