I found the hose that is hissing it comes from a black canister on the drivers side firewall. Then goes up to the "vacuum tree" on the intake. The side closest of the little quarter sized one way valve is hissing really bad....can that little one way valve go bad and need to be replaced or what? Thanks guys.
