What is this part called.. Vacuum Problem~!!!!

[romansoldier100]

I have a rough idle, I was looking around the engine bay and noticed that the vacuume line that goes into the firewall, like a black round 1" valve. It has no part # on it, but there is a large vacuum line that goes off of it, and there is also a small one. The small one broke off. So I need a new one. Anyone know what it is called?

Its a vacuum valve of some kind that goes right into the first firewall, and then into the secondary air pump IIRC. Please help!!! I can go take a picture!

I will post a picture this weekend. The part is numbered 8E0-611-933. I ordered that part number from ECS. Its not the same part. Hopefully the picture will clear this up. When the small hose is leaky or disconnected. The car stalls at speed randomly and it throws check engine, epc, the traction control light and sometimes the oil pressure screen. When I turn the engine back on it runs fine again and most of the time the lights go away. Sometimes the epc light will stay on until I clear it.
