Air leak around my intake manifold - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I've got a small air leak somewhere around my intake manifold. I can't put my finger on it, but I can hear it when it is idling, and it has a horrible idle. If if sits at idle long enough it will cut off. I've had the problem for a long time, and I realized one of my vacuum hoses was shot on my EGR. So I removed the whole EGR and capped it off. And capped of the hoses for it. But, the problem was still there and now it is getting worse. Please help if you can. Thanks.

sounds like you still have a vacuum leak somewhere. I would suggest looking all over the engine bay for more vacuum leaks or you can go to this site: http://www.vfaq.com/mods/ICtester.html and make a homemade leak tester to better pen point the problem.

Or just spray carb cleaner around the area and when the idle rises you know you've found your leak.
