is the bov vented? if so, then bingo we have a winner.

My car does the same thing, it's like bigglesworth said if your bov is vented with no return to the intake then when you let off the gas your car will actually "flood". I understand this is because the computer can't monitor the amount of air being released through the bov and therefore continues dumping fuel into the engine. This is fixable by installing a GM MAS in between the bov and the throttle body, or buy a bov valve that is recirculated into the intake.Until then just feather the throttle as you slow down. Oh, the remedy for starting a flooded fuel injected car is actually holding the pedal to the floor as you crank the engine, just let off as the engine begins to catch. This may not be the "proper" way, but i'm not an auto mechanic. Good luck
