Hi guys.I've been having problems with my wife's 1995 Nissan Maxima. It stalls out quite a bit at stop lights when idling. This occurrs more when it has warmed up but not all the time. I discovered a vacuum port on the bottom of the throttle body which isn't connected to anything. One vacuum hose is connected to the bottom, but the 2nd one had a broken hose connected to it. Where does this port connect to? Any help would be greatly appreciated.

One of the ports has what looks to be a broken hose on it but it is actually a cap the other goes straight down to the metal tubing check the pcv valve located on the top in the space of the upper air intake manifold on the valve cover itself clean the egr valve assembly carb cleaner works nicely for this and them check the idle air control valve to see if it is sticking last resort Mass Air Flow Sensor cause it is the most expensive
