2001 RACING IDLE SPEED

2000 Honda Odyssey • 54,345 miles

When I started the car few days ago after using it last on August 10th 2011, the idle speed racing up and down when in park and neutral but ok at drive gear.I like to know what are the possible causes.I did not notice any engine light on.

It sounds like a bad idle air control valve. It is located on the throttle body. Check that. Also, check for vacuum leaks.
