Escaping air noise coming from Engine

I hear some air escaping from what seems to be a small box attached to the right side of the engine just behind the dipstick. The noise is pretty loud hissing sound and I do not know what is causing it. Is this normal?

History:

I have been having issues recently (this winter) where the car starts violently upon cold starts. At first I thought is was due to the extreme cold weather here in MD, but it has been warm the past week and it still happens. Idle above 650 it seems fine, but at 550 it is rough. Twice it would get to the point where the car would not start (or actually cut off after starting) and I would have to jump it.

Codes thrown:

p0313, p0300, p1343, p1345, p1347, p1348, p1351, p1353, p0174, p0171. These appear to be related to cylinder misfires and the 017x, which I knew about already, is the fuel leak.
