In Reply to: Whistling/hissing sound from under intake manifold posted by John L on October 23, 2000 at 03:23:24:

manifold and check the vacum lines there for cracking or being disconnected.

I've been having this sound for quite a while. The whistling/hissing sound seems to be coming from underneath the manifold.

I guess when i get the chance to take the manifold off, i should also clean the ICV eh??

What could the sound be? Vacuumm leak?
