So I'm driving down the highway today with the AC on and I get off and am idling on the offramp. I first notice that the tach is idling around 1200 and every couple seconds bounces up to maybe 1400. Then I notice there's an unusual amount of vibration...so I turn the AC off as I start to move again. The next light I hit I have the AC off and the car idles fine. Any ideas what this could be?

Thanks.

Yeah, mine is in the 600-800 range normally. So it was idling much higher than normal anyway and going even higher every couple seconds before returning to around 1200.

When you idle the fan sound you hear along with the slightly higher RPM is the radiator fan I think. I remember seeing on the WRX brochure that a low rpms this happens.
