Im sorta confused by the idling in my M6. Its almost as if the car knows when I come to a complete stop. If I am driving down the road and I push in the clutch the car will idle at about 1500rpms. Once I come to a complete stop, still holding in the clutch, it will drop down to idle at around 900 rpm's or so where it should be. Its like the car knows when I stop. It doesn't really make much sense to me in a M6 car. Any ideas about this? Thanks. -Matt
