So first off, this is not my Protege. Will take some pics later, but I'm asking more about a certain hose. It is circled in red and connects somewhere back where the arrow and "X" are in blue. I noticed that it was detached and was told by a friend (I know) that I should be able to just cap it and be good to go. It just seems like air goes through it. Does anybody here know what I'm looking at and if I would be okay to cap it?
Bowing to the Mazda gods,
