    No, raw gas entering the charcoal cannister is usually due to overfilling the fuel tank or improper venting of the fuel tank. The purge control valve releases the gas fumes that are supposed to accumulate in the cannister into the intake manifold when told to do so by the ECM module. A faulty purge valve that stays open all the time can effectively cause a vacuum leak. If it remains closed all the time, it can cause the same symptoms as a saturated charcoal cannister.
