Is your check Engine light on? Does it idle high as well or only in gear? It's more than likely a pretty big vacuum leak or TPS (Throttle Position Sensor), and possible the IAC (Idle Air Control) Valve. If there is no check engine light, have a smoke machine hooked up to the intake somewhere and you should find a vacuum leak.
