Likely an issue with the TPS sensor on the bottom of the throttle body. Could be a few other things, which you might try first - I would try cleaning the throttle body with throttle body cleaner, and what's the idle rpm? A previous owner could have adjusted the throttle stop and gotten things screwed up.
