Drive it for a while, next time you start the car and when the engine is warm (that engine oil temp thingy), the idle rpm drops significantly to roughly 500 rpm.

Thats the way pretty much every car is designed. Its to help the car warm up faster. IIRC it also has something to do with the catalytic converters getting up to temp.
