can someone help me identify this tube?
<center><img src="http://pictureposter.audiworld.com/86540/img_7156.jpg"></center><p>Anyone know what this tube is used for? One end is attached to a braided hose at the bottom of the black round plastic thing in the picture and the end with the rubber tip I have no idea where it goes. In a failed attempt to replace the CTS, I had to moved wire clusters out of the way. As I gave up and started putting everything back in place, I noticed this tube hang or actually pointing up with the rubber end not attached to anything. I was able to start the engine and it ran fine but that was only for a few seconds. I don't want to start driving it tomorrow and have something fail on me because this tube is not in it's proper position. Any help would be appreciated!

That probably hooks to a vacuum source on the engine itself. Start by looking at the intake manifold
for a nipple with no hose. That looks like it probably has to do with cold start emissions stuff. You probably wouldn't have a running issue but might throw a code.

Just did a little quick reading
If that tube is going to that black round canister type thing then that is the vacuum signal tube for the variable intake solenoid. I was wrong about it being for cold start, apparently is is for tuning power delivery and optimizing fuel efficiency.
So you still should look around the block for a vacuum source but if you don't hook it up, you might not run as well as usual and probably will throw a code.
You should break anything but you do want to find the vacuum source for that sucker.

well...searched again this morning and couldn't find where it goes
It's only a 5-6 inch hose so I searched a 6 inch radius from the vacuum pump looking for an outlet to plug it into...but nothing. I took a quick drive with the hose disconnected and it didn't seem like it had any effect. I guess I'll be ordering my Bentley manual today. Hopefully nothing will break in the next 4-5 days until it gets here. I hope when I get the manual, I'll be able to help someone else on the forum.
