but if you have high HC & low CO its lean as the fuel molicules arent close enough to get all burned thus the unburned HCs
just get your wideband on it & set it up for stoich part throttle & cruise
with a good cat this should work although closed loop operation where its swinging lean & rich actualy allows the cat to do its job better as on the lean side more of certain gasses are produced which are then split up & combined with gasses produced on the rich swing which are also split up on a molecular level I combined idealy to make carbon dioxide & water vapor cats are actualy pretty cool things :-)
take care
