I seem to be having a little problem with my throttle... when my car gets warm the throttle seems to be getting stuck. When I pull up to a stop sometimes the car wont idle below 2000 rpm unless I rev it a little. Even if I drag the rpms down with the gear, as soon as I push in the clutch it revs back up there. This usually isnt a problem until its warmed up a bit. I lubed up the throttle assembly on the engine and it seemed to help with the frequency of it but it is still happening. Do I just need to spray the throttle with some carb cleaner or something?? Its a 98 Cobra and Im taking it on a 3000 mile trip in two weeks--hoping to cure it b4 then. Thanks for any help!!
