I wonder if it's the hamsters blow-drying their hair?

That is an odd one. I've had newer vehicles with secondary air injection (two GMs) where an electronic air pump would blow air into the exhaust at certain times, but never with the vehicle off.

I wonder if it's got something to do with the EVAP system on the latest PZEV Scoobies? A vacuum pump or the likes?
