Why does the engine rev up to 2500 rpm upon starting and while in park?

(1994 Oldsmobile Cutlass Supreme)
in Fayetteville, WV on April 20, 2012
My car goes up to around 2500 rpms when it is started and when it is stopped and put in park gear. It also runs pretty fast without the gas pedal being pushed when driving. I have to use brake to maintain speed limit. I replaced fuel control sensor. It did not help.
