OK, I cleaned by TB recently and connected back up all the hoses going to the main intake hose. Here's the thing though, and I'm sure I did not remove this one. I noticed that by the intake hose on the side closest to the airbox, there's now a J shaped hose pointed downward that does not appear to have any place to hook up to. It's not a vaccuum hose, as I've put my finger over it. Is it some kind of vent hose? Anyone know what I'm talking about?
