On my 2004 Dodge 2.0Sx I just recently noticed that a hose was off and is not connected to anything. The hose comes off the top of the engine blows out exhaust. I checked and there is still exhaust coming out my tailpipe. Therefore, I am wondering what this hose maybe and where it should be connected?

 

There are several hoses. You need to be a bit more specific.
