The fittings that connect to the head and there are two of them are made of plastic which obviously being plastic and so small are both broken probably due to engine heat and the hoses connected to them at just sitting there and its running rough on idle and when the aircon is turned on. If I know what these fittings are called I can order new on ebay so Im looking for the name of the parts, I cant just order vacuum hose engine sensors they must be called something, widget, gizmo, etc?
