Honda Odyssey Idle Problem

We just had our 99 Odyssey serviced before going on vacation. Everything seemed fine but we noticed that whenever we parked the car without turning it off, after a few minutes it would intermittently go from 1000 to 2000 RPM back and forth. the any ideas why our car might be doing this all of a sudden? thanks in advance for your help …

A vacuum leak can cause erratic idle speeds. So can a problem with the Idle Air Control (IAC) valve.
