Hi there everybody, I'm not too knowledgable at all about cars yet, and I was wondering about this little part of a hose that sticks out. If I plug the hose, the engine idles a little higher, And I don't know where the hose originally went. The hose is circled in the pics, just wondering if anybody knew what it is going to/coming from, and if I should re attach it somewhere, or just plug it off.
Sorry about the blurry pics, my camera is cheap. Thanks to all.
