Vacuum tube to the right of the lambda?

Hey guys, another round of whatisit... Maybe 2 inches to the right of the lambda sensor, vacuum "nipple", near/on the exhaust manifold. Thats about as descriptive as I can get. It looks like it should have a tube going to it but mine looks like it was chopped off (??) Has the remnants of a vacuum tube still on it. What is it and where should it be going? Thanks in advance.

Nipple

Sounds like what you are decribing is the line for the 5th/6th port actuators.

ok sorry for the nub moment here... so this nipple activates both intake and exhaust ports (5th and 6th) from exhaust backpressure? Or am I really confused? Where is it supposed to go? I'd assume not into the normal vacuum system.

exhaust backpressure, activates the intake ports. There are only intake ports, and the exhaust backpressure activates them via a metal line from the cat/presilencer to a rubber vac line that branches off to the ACV and one small one to the actuators.

Ok gotcha, I can't find anything left of this tube anywhere in the engine compartment. Could you describe where the tube should be run? Would this cause a 1200 rpm minimum idle?
