nkx Posted July 7, 2005 Share Posted July 7, 2005 ive become aware that i have a vacuum leak. im getting 11-12 in/hg at idle. i guess its been there for while, just didnt really notice it. the car idles kinda funny, seems like theres no low end at all. it wont stall at idle. i tried to look over the hoses as best i could, but i didnt see anything out of order. i sprayed some carb cleaner, that didnt do anything but make my engine bay a fire hazard :-\. i think my next step will be to try to blow some compressed air into the intake, and spray some soapy water on the engine bay and look for bubbles if i cant find the leak with suggestions here. are there any spots where i should look in peticular for leaks?

Cougar Posted July 9, 2005 Share Posted July 9, 2005 Did you check the intake manifold gaskets for a leak? If that is ok you could try disconnecting hoses and plug the port while watching the vacuum gauge for a increase in vacuum to try to find the path the leak is on. If you have a automatic tranny the modulator may be leaking. Quote Link to comment Share on other sites More sharing options...
wintersubaru Posted July 9, 2005 Share Posted July 9, 2005 If its carbed check the choke hoses. I had one there and because the hoses are so small its hard to find. Quote Link to comment Share on other sites More sharing options...

nkx Posted July 11, 2005 Author Share Posted July 11, 2005 i cant find this freakin thing... i took off the 4wd plenum, looked in there and the TB, nothing out of place there. i replaced the AAV hose because it looked kinda nasty, that didnt do anything. clamped everything back up tight... still reads 11-12" of vac on the boost gauge...
