Sounds like abad PCV hose. Often when these get holes in them the rpm's will race. Check this hose for a leak or soft spot---replace it if needed. Often you can hear the vacuum leak if it is the pcv hose. The PCV valve and hose is located behind the intake manifold, the hose is about the diameter of a quarter. If not leaks are found, check the throttle body gasket for leaks as well.
