what are the symptoms of a bad throttle? on 2002 Chevrolet Trailblazer

Whitout warning, my '02 trailblazer showed a "check engine" light as well as a "reduced speed" light....the car will not rev up above idle, but I ran it for enough to get to repair shop. The repair shop just called to say I needed a new throttle body. does this sound right for the symptoms I just described?

yes it does most likely the throttle body electronics has gone bad
actually ANYTHING would sound right...bad transmission solenoid, stuck P/S switch, low vacuum reading, lost cam or crank synchronization, low charging voltage, take your pick...or add to the list.
