I just purchased a SWEET 2004 Tiburon GT 2.7 6 speed. It is all stock. I recently had a problem of coming to a stop and the idle reving to 2500 RPM and staying there. It doesn't do it all the time and it has only done it on warm days at normal operating temperature. I tried pulling up on the throttle pedal with my foot, but that did no good. The dealer has had the car for 3 days and they tell me they can't get it to do it. Anybody have any ideas? Is this a common problem for the Tiburon? Any help[ would be appreciated.
