This is probably pretty vague, but I have a code P0411. I found a braided line directly underneath the middle of the intake manifold that T's off of a rubber hose. It folds under towards the fire wall, but was not connected on the other end. Does anyone know where the line would even go or have some type of diagram showing where the vacuum lines off the intake manifold and around it?
