Is it an aftermarket BOV venting to atmosphere? If so, then that's very likely the cause of your problems. It isn't that the air isn't released properly, the problem is that the computer is expecting that air to still be in the system (because of the factory BPV). Since the air isn't there, the engine runs extremely rich during shifts, and this can be enough to stall the engine.
