If the symptoms happened while moving and braking, coyote might be on the mark. Since it happens at idle there is no logic to the brake rotors. I would start by checking the motor mounts. IF you brake rev it, both reverse of forward, is there much movement?
One other note to coyote, it is rare that rotors can be turned anymore and not end up pulsating a few months down the road. Not to say that will happen, just what I typically see.
