when putting my intake manifold back on I realized there are 2 vacuum lines coming off of it that goes to a line that runs along the fire wall and one that connects to the valve cover.
my question is
there is a vacuum line coming off of the throttle body with a little box in the middle of it that leads no where. it attaches to the back of the manifold but has not port to connect to.
i have a 05 model, i dono if this is different compared to other models
i have a diagram that i can upload later as soon as i figure out how to save it as an image file
