Bought a new GT Saturday. While caught in traffic on the way home the throttle "stuck" at about 2500 rpm. I had to blip the throttle a couple of times to get it to come down. Called the dealer yesterday to schedule the 600 mile service and told him about the throttle. Now I need a new "...air box." On the way home yesterday in DC traffic the throttle stuck probably 10 times. Has this happened to a lot of the new GTs?
