    What is this vacuum hose?

    Does anybody know what this vacuum hose goes to (it just disappears in the fender) and if it is mission critical? It comes in to a port right behind the throttle body. The hose is pretty old and porous. I'm on the hunt for vacuum leaks and I'd like to unplug it to test if this is the culprit...
