So this is what I found when I thought I might have a vacuum leak under the hood.

 

 

This is the joint that the line goes to.

 

 

This is what is sticking out of the hole.  To me it looks like the plastic connector broke off for this line but I can't seem to find where it might have connected to.  I tried to figure it out using my Chilton's but am a little confused by the charts.  Any help would be appreciated guys.  Thanks a bunch.

The end of the hose looks like it broke off either the EGR solenoid, or the purge solenoid.

I still not too knowledgeable about cars.  I do know what the general look of most solenoids are but I can seem to find some thing that looks like a solenoid that is broken.  I am also not adept at reading the repair manuals yet so I am not even sure where to look for either of those solenoids.  Any chance someone could post a pick of what they think should be connected to that vacuum line?

What does the other end plug into?

The other end plugs into a three way joint which plugs into another three way joint and a few other items.  I haven't had a chance to take some other pictures but I will as I can.

just plug it for the meanwhile and see how things are ?

So I plugged the vacuum line with a screw and now the engine seems to run smoother.  Still not sure what the line goes to.  I looked up pictures of the EGR valve online but can't seem to find anything that looks like it under my hood.
