there are 3 nipples for vacuum lines on my intake manifold and one of the lines is missing and nobody seems to be able to tell me where it connects, I cant seem to even find a diagram of the engine so that I can fix it myself. You can hear it sucking air when the engine is running, and it is getting way too much oxygen causing it to burn gas like crazy, can ANYBODY tell me where the 3rd line connects, it is the one closest to the driver side... signed frustrated feline
