- Fri Jan 11, 2008 4:03 am #37267 I first though my brake booster was going bad, but after further analysis I have figured out I have a vacuum leak some where close to the firewall.

After searching today, I found one hose that was open, as you can see in the pick below circled in RED.

Is this supposed to be open and what is it supposed to be?




Thanks!

+1 This is the way you find a leak.

That hose in your pic is not the reason. I don't know what it is for but I have the same open hose and my idle is perfect.

- Fri Jan 11, 2008 8:07 pm #37351 My idle is totally perfect and the car runs great. Even the MPG is great.

My car is a 95 civic DX AUTO, I imagine its the original motor, but i did buy the car used from a dealer, so no telling what the previous owner did.

A vacuum leak WILL mess with your idle.

Any chance you're just hearing your intake whistleing??

This sound is coming from really close to the firewall.

- Mon Jan 14, 2008 12:52 am #37511 sometimes a hissing noise can be coming from the throttle body. I've heard it on a lot of civics, including mine.

That sounds like it could me in my case too. If it is coming from the throttle body is this something I should worry about?
