I never noticed it till my car started idling funny every now and than, bounces from 200-1000. Me and a friend popped the hood, found this- when we covered it with our finger the weird idling stopped. I dont know where it goes to- or if it was ever connected but the problem just started. After i took the pics i got a small peice of tube with a screw at the end of it to stop the problem for now- but id like to fix it correctly. Thank you




The other one next to it is connected- im talking about the one next to it. Thanx for any help.

 

that hose you have next to it is what that connects to ill have to look and see where it ends

 

Probably the nipple for the butterfly in the stock intake. You have an aftermarket intake so you don't have it hooked up anymore, just get a vacuum cap and cover that nipple.

 

i have an aftermarket intake and thats still connected. when i get home from work ill try and follow to see where it connects

 

it is connected to EVAP SOLENOID VALVE according to the diagram I have from the repair manual

 

cap that bitch

 

Well, considering there's an open nipple and a loose vacuum line right next to it, CONNECT THEM!

[edit]The vacuum diagram that 92_VTEC posted is correct. It goes to the Evap solenoid, which if you follow the top hardline, should be connected to that.

 

It looks to me like you are missing the vacuum line marked no. 8 (to the intake control check valve)...what engine? 'cause it may be different for the JDM H22A....my 2 cents

 

Lookin at the diagram i am missing the #8 lines- not the #20. I guess i'll just cap it.

You could cap it or what I did when I had my civic (D16) was use a breather filter. Though it may not solve your idel problem.

 

Woo! I was right It doesn't matter what you have connected to these nipples, vacuum is vacuum with the exception of the brake booster and PCV which have bigger lines. So, yeah just cap off what you're not using...

That's retarded to put a breather on a vacuum line...it's still going to cause a bad idle because the line would still be open.
