SOURCE: sticky gas pedal
it is a dirty throttle plate. $280 is an absolute ripoff for a cleaning, it is about 10-15 minutes of work. They are probably quoting replacing the throttle body which about a $150 part.
Got to Autozone and get "CRC Throttle Body Cleaner". Remove aire inlet hose at throttle body with a screwdriver. Spray a *small* bit onto throttle plate, use clean rag or qtips to remove gum/varnish. Spray pivots and also clean around perimeter of the plate. Take it to an independent mechanic if you are unsure of the procedure.

SOURCE: no acceleration at high RPM's
It's probally the fuel cutoff.If it's in Park Or Nuetral this is a normal condition to protect the engine from overevving.If it doesn't do it in gear that's what it most likely is.hope this helps

Your noise sounds like it is power train related,If you have eliminated the engine,Since it doesn't make the noise while moving and in neutral.
It sounds like a universal joint in the drive shaft.Do you notice a vibration
along with the noise?

Try cleaning the throttle body. Use a throttle body cleaner and do not flood the throttle body with the cleaner. You will have to open the throttle up and spray around the butterfly. It most likely carbon buildup and causing the butterfly to stick when you accelerate. A couple of short sprays will be fine, clean with a cloth. You will see a lot of black buildup flow out of the throttle body. After you wipe dry, let the intake hose stay off for a few minutes for the throttle to dry out.
