VACUM LINE 300 1990

Hello, I have a 90 740 that I bought to fix up for a family member and it has a vacum line that is pluged with a screw and I cannot figure where that line is supposed to go. it is in the middle of the intake manifold, the second one downhas a cap on it, it is the one beside it. I have a rough idle, I assume this could be part of the problem.

Thanks
Dennis
