What is that hose about?
Ok so you know where your MAF is right? Well right behind it there is a hose that runs from the bottom of the intake tubing into the manifold....what does it do?

i have no idea what it is, but i once was looking at my filter and accidentally disconnected. th engine wouldn't start and it took me 15 minutes to realize it had fallen off. it was bizarre and pissed me right off.

Ok there is only one hose that leads off of the bottom of the tubing directly behind the MAF. I had the same problem you mentioned earlier when I did and induct service to my car. So I would gues it is probably 5/8 in diameter....i thought it might be a oil thing, but then why would it lead to the side of the mani? why do they need to put a vaccum hose right there? what purpose does it serve?

I've disconnected that one, too - once
As described, the engine acted like it had a huge vacuum leak.

does anyone know if it is safe to by-pass this hose by plugging the tube and putting a breather filter where the hose is? Or maybe just plugs?

not sure, but i think you can leave the hose off. it is definatly safe short term, not sure about the long term affects, if i dont get off my lazy *** and get to autozone to buy vacumn tube, i will be able to tell you the long term affects, if any

IAC hose does not appear on the PCV diagram.
