Default rough idle

Today i was driving back from a cruise with some friends. As i pulled up to a red light and was at a stop, the car began to "shake" at idle. Nothing too hard...but you could just feel it in the shifter and a little bit through the seat. After 2000rpms it goes away and everything is fine. No ticking or tapping noises. And i wasn't getting on it before the problem came up, so there wasn't a loud bang or a pop in the motor. The only thing that was out of the ordinary was i hit a pretty decent sized pot hole at about 15mph.

I took it easy coming home and let the car sit for about an hour, started it back up agian and it still has the shake at idle. I've done a few searches on some Subau boards but i just wanted a 2nd opinion.

no, it's not idling low and the BOV isn't recirc but it hasn't been for about 2 years and this hasn't happened before. The idle doesn't studder it just shakes pretty bad. I popped the hood and just let it idle and the motor is literally shaking in the engine bay...it's a smooth idle, not choppy but the motor just looks really loose in the engine bay.
