I'm in the process of doing the vacuum hose upgrade, and while I was doing it, I noticed there was a vacuum hose missing. Does anyone know where this runs? (it's the open tube above the green in-line thing) Whatever it is, i don't think it's ever been connected. Perhaps it's why i've never been able to fix my idle?

 

It's only connected if you drive an auto.

 

That is correct!

 

Thanks so much! That puts my vacuum leak fears to rest

 

check out my guide on rats nest vac pipe replacement, it has all the info you need:

Nice write up dude. I guess after I get my boost gauge on and the AST replaced, this'll probably be the next thing to do. Thanks!
