If it's that small black hose, it goes to the back of the intake.

Thanks for the quick reply. I have another hose coming from the wire loom plugged into the back of the intake right next to the MAP. Where does that one go?

Not the one for the PCV. I know that plugs into the valve cover. It's the smaller diameter one.

The hose i've circled is the one I was originally talking about. It's for your AIR system and goes to the back of the intake.

Well chese, The car has been mine since new I have done everything on this Car(including removing the AIR) and I never remember seeing that thing. Now let me ask you this, there is another hose running from that device that I have running into the back of the intake, what should I do with that? I don't want to have an open hose coming from the intake manifold. Thanks for the help guys.

that other hose you plug it up with a screw, for example, so you won't have a vacuum leak. i put some electrical tape over the screw to prevent it from falling out.
