As putting my motor back together, b16a in a crx, i cant seem find where this hose go to, i connected to this black box right under the manifold, but it revs up to 2k, but if i were to use my finger to cover it, it would idle normal, anyone has any ideas where this hose goes to? Thanks for looking!

 

what Intake mani is that?

 

looks like a type R / blox?

 

on my b18 its blocked off.

 

It goes to the pcv valve

nice cusco bar by the way

 

thanks for the comments and replies, but yeah i found that it goes to the pcv valve, then goes to the black box thing under my manifold.. appreciate it!! and its a skunk2 manifold by the way....
