I went looking for info..found this: http://www autoshop101 com/forms/h64.pdf.
Since all 3 readings are NOT out of spec, the cat might not be the suspect.
If I'm reading the charts right, it says high NOx would indicate that it was burning lean - the catalyst needs CO and HCs to convert the NOx to NO2 anc CO2.
Since your NOx isn't high, but your CO and HC are, that indicates that you're probably running rich.
How old is the O2 sensor?
