Remember it's all manifold vacuum, so the number of ports are dictated by requirements of the vacuum accessories on the car. As long as everything's hooked up and nothing's left open, don't worry about it. The fluctuating idle could be several things. First make sure the idle air bypass is clean and I mean CLEAN. Same deal with the EGR valve. Next you need to reset the idle parameters. Click here to find out how to reset the idle correctly. Good luck.
