Another hose not on vacuum diagram.

This one is on a little black module. The black module is saucer shaped and comes off the bottom of the #2 air control valve on the reed valves. It is NOT the yellow line from the #2 air control valve. My questions is where does the other end go to?



My index finger is disappearing behind it.

And the diagram.



I'm pretty sure all other connections are found and done. I'm still getting a really high idle (~1500-2000 rpm) and the poor thing stalls when stopping like 20% of the time.

Thanks,

Marcus
