I suspect a large vacuum leak as that would affect 3 of the 4 codes I could find. Check all cloth covered lines, hoses and check valves around and under the manifold and the one going under the coolant tank towards the fender. The suction jet pump may have failed, but you should have some misfire codes with a large enough vacuum leak.
