    they seal shut until you hit a certain engine speed when it opens. Car will not run correctly at low speeds if the valve does not close fully

    Yes you can bypass it by unplugging it but it will show up a fault light. Problem is tho yours is not shutting correctly so unplugging it will not help. You can get it mapped out but you will still have the same problem until you can get it to close or put a blanking plate in
