Searched this mysterious "charcoal canister bypass valve" and apparently it is only on the US version of the car to pass our standards of emissions. Some guy was having starting and idling issues so he pinched off the tube that goes from the canister to the valve itself and unplugged the valve's connection and his car runs fine now. its not like an old car has to pass emissions (at least thats how it is in Mass) thanks for the responses everyone!
Ill be getting it together 2morrow hopefully! if the BavAuto shipment comes in. ill be back on here to let you guys know if you need that stupid thing!
