A friend of mine has an 01 ZO6 and its stock except for exhaust and intake. We tweaked a few things on it for gas mileage but nothing major. The car suddenly decided when you press the clutch and are coasting to a stop, the car idles down to 500 rpms and sits there. Then, once you've come to a complete stop, raises up to where it's supposed to be idling. I know I've read about this before but I'll be damned if I can find it now. TIA.
