Brief RPM dive when stopped.

While Jordo!'s bad sensor diagnosis has a good chance of being correct, I'd try powering down the ECM first. It's easy to do - remove battery cable and step on brake pedal for a few seconds, then reconnect battery. The car may run rough for a bit while the ECM relearns the engine and you'll have to reset the windows (procedure has been given many times; use search). You may also lose the radio presets.

The battery was the issue in my case... if anyone was wondering.

Which battery did you end up purchasing?

Figured -- glad its fixed

Actually, my idle was intermittently doing this tonight out of the blue...

I'm probably about due for a battery too... I'm due for an oil change in another few weeks or so. I'll check the battery then.

I ended up putting a light weight battery in my car:

I originally thought about putting in a lithium ion battery but it was cost prohibitive. Here is the thread for that:
