Have the throttle position sensor checked. Also, make sure the engine is actually revving that high -- is it accompanied by a different engine sound? It's not unheard of for the tachometers to go bad in the dash cluster -- I had one in a Chrysler Sebring that literally had a mind of its own after about 70k miles.
