Erratic idle?

[Caymanized]

We had drove across town last night, just barely enough to get the engine warm, and when we got home and got it parked, it started surging at idle, like the RPM would drop and return to normal and repeat for about 3 or 4 minutes... started it back up and it didn't happen again... Any thoughts? It has done it a couple of other times, but only happens in park.

Thanks! I'll get that checked and cleaned, and I'll update if there is an update!

Is it possible this will cause shitty fuel economy if the IAC is stopped up?
