Positive Crankcase Ventilation. Looks for all the hoses going into the intake from the valve cover and the gray can on the front of the PS valve cover and clean them all out and replace as necessary. The gray can you take off and soak in fuel and clean out the wire wool or what not inside. Yes, breather hoses. I think there are two, but I would have to look to check (I know GEMS 1997s have two, but I have to go look on a 1993-95 to be sure as I don't have the image in my head beyond the grey can breather thing).
