    Why does my spark advance drop far enough to cause a stall condition at idle?

    I am trying to understand why my spark advance drops and causes the car to stall or nearly stall when coasting up to a light and/or (to a lesser degree) when sitting still. This does not happen all the time, but often enough to need fixing. The attached scan shows my attempt to keep the car running by opening the throttle. The car is a C5 with LS7 (242/248 @0.050" cam) and runs ok otherwise.
