Vestigial nipples on my PCV plate?
I did the pcv plate / intake manifold gasket replacement to smooth out some idle problems and 1222 (o2 lamda control) bug and while doing so I noticed on the PCV plate (rear of intake manifold) there are 2 nipples of equal size (roughly 1/8 inch diam.) - I know one is a vacuum line to the fuel pressure regulator but what's the other one for? I just plugged it up for now but it MUST be there for a reason.
