Try this from a different angle. Was your defroster on? How about your A/C?

Also check your PCV. PCVs get grindy and dirty and start to stick after a while. They're all about vaccuum so they're all about idle as well. Plus they'relike $2.00
Here's a link:

I wouldn't like an idle at 500 rpms anyway. It should be at about 650-675 rpms. Like everyone said check the IAC, MAF sensor, a tune up couldn't hurt, and check the fuel filteer.
