Occasionally while driving my 99gt i seem to get stuck at a high rpm.

I can take my foot off of the pedal and the car will push itself along, on a level road I can maintain 30 or so mph without touching the pedal.

If I put the car in neutral and turn the car off then slow down to about 15 mph and turn the car back on it fixes the problem 95% of the time.

replaced Tps and had the cruise control checked over....;crap

Mine would do this every once in a while back last summer. I got off the Freeway and wham, my car was stuck revving 3k in neutral.

Check the TB for stickyness and make sure your Throttle cable isn't hanging up.

Also Check the Vacuum lines, I had a vacuum leak and that was causing my problem, it was strange.
