2006 Dodge Stratus SXT 2.7L

There is a plastic tube that connects on top of my intake manifold that is not connected at the other end. I have searched and searched and I cannot figure out where it goes. It has a 90 degree rubber boot connecting it on top of the manifold, close to the throttle body. It is about 12 - 16" long and formed to a specific shape. There is a 3/8" rubber hose on the end and a small plastic nipple after that. It looks like it should connect to another hose but for the life of me I cannot find any hose, hole, valve, or anything else where this thing connects. The car will not idle long and when it does it idles badly and I think this hose/tube is the key. Can ANYONE tell me where this hose/tube/thing/deal goes?

 

A lot of cars have a vac diagram right under the hood,a sticker right on the raditor support, maybe somewhere else!

 

Thanks D Ryan but the veti sticker only shows which components the vacuum hoses are connected to. It does not show their specific location.

 

I finally found it. The tubes routes down the right side of the engine, across the transaxle (going towards the rear of the car), turns right towards the right side fender (standing in front of car), then to a valve mounted on the right side fender just below and to the left of the master cylinder. Could be EGR vavle, I can't tell. Wiring harnesses and other hoses make it hard to see the valve.
