Check that Air Conditioning isn't on - that calls for higher RPM (tho typically not 1,000). If A/C is off, then it's the fast idle (I think) which is controlled by the engine computer. Used to be the fast idle was mechanically set, and sometimes it would stick - "punching" the gas pedal hard and fast would often release it. I don't believe that's the case any longer.
Any other opinions?
