I've been working on a 993. Got it all back together and there are three plugs on the driver side which don't seem to have a place to go. All three plugs are two prong and have yellow gaskets inside. One plug is long enough to reach the distributor and according to another thread may not go anywhere. I checked another motor (different year-aluminum manifold) and it has two air valves with two prong plugs on the manifold, which the car I'm working on (Black plastic manifold) doesn't seem to have, or at least I cant find them. Am I missing something or are these plugs not used?
