That's quite a bit of revving for sensor problems. I think I would look at the throttle itself to make sure it's closing fully. The cable could be hanging up or the throttle could be sticking in the throttle body. Also check the linkage inside the cab and on the engine.

You may have to try a little penetrating oil on the cable/linkage.

Hope this helps.
