    Anyone had this problem after pulling of the exhaust bypass vacuum hoses?

    Do the hoses have to be plugged? I saw dealer installs of Tubis without the hoses plugged.

    Thanks.

    Absolutely essential unless you pull the electrical plugs off the solenoids otherwise air gets drawn into the induction system causing a lean signal
