No but it should not be idleing that high...have you checked your idle sensor? That was a problem for me once....
Hope this helps, Mike

COuld also be a vacuum leak. The idle speed is saet by the ECU and 100% computer controlled.

There is a screw that adjusts how far open the throttle plate sits at idle (almost an idle set screw). You have to grab it with pliers to adjust it (turn it in or out). The idle is maintained by the idle air control motor. It allows a certain amount of air to bypass the throttle plate. That motor is pictured below:

if you look where the throttle bracket rests on the tb, you will see a screw that it rests on. on the back of that screw there is a metal plate (cap). drill a small hole in the plate, take some needlenose pliers to that hole and pry the metal cap out. your idle can now be adjusted with a torx driver. i had this done when i got my tb bored. all 2gnts have it, its just covered up.
