T/A has High RPMs when driving
I have a 99 T/A, as i was driving today the RPS stayed @ 2900-3100 RPMs when i would try to shift. It acted like i was giving it throttle the whole time. When i was going to stop signs and red lights i would place it in neutral but the RPM stayed in the high range. The only time it would drop is when i was at a complete stop, Even when i was coasting at a couple of MPH it would stay close to 3K RPM. What could be telling it to rev up on it's own? Thanks for any info

Could be tps or even the idle air controller going bad. But if this has been happening since you got the car and it has a tune, it could be tune related with the throttle follower /cracker tables. Also check that the idle set screw isn't too far in or if someone drilled too large of a hole in the throttle blade. If the car is stock, you probably only have to worry about the throttle position sensor but I've heard of vacuum leaks causing this too
