You are missing a part in your vacuum hose called a purge solenoid. It will allow vapors from the carbon canister to be drawn in to the intake to be burned occasionally, but not all the time. It is roughly an inch around and 3-4 inches tall, has 2 fittings on the bottom and 2 wires out of the top. Your connector should be around there somewhere. This is all from memory, so if something doesn't sound right, let me know and I will check into it.
