Anyone know what this is?
Im kind of simple when it comes to cars, learning a little at a time as various things go wrong with my 94 tempo. there is a black circular type of thing to the front and left of the airfilter. it says "BR 4a11B" on it, among other numbers, and it has a hose that seems to be running from the air filter, into it, and another hose leading out to the bottom of the car.
the hose leading (away from?) it at the bottom has become unattached where it it supppsoed to meet some kind of pipe, i think because the metal has corroded. when i put my hand in front of it (the pipe-thing it is supposed to be connected to), i can kind of feel some air sucking in a little.
i thought it may have been something to do with the a/c, but now im not so sure. if someone could tell me what this is and what the implications of that corroded, now disconnected, hose are, i would be most appreciative. im not sure how long its been that way. thanks much.
