Running slightly rich, and perhaps the cats were on their way out then. Make sure all the emissions equipment is functioning (No OBD to tell you it isnt), check the plugs, filters and timing and make sure the car is fully warm (20-30 min driving) before having it tested. It cant hurt to go over the car and have it tested again *if* you find something off (busted EGR, timing off, etc).
