running lean

%CO2 14.6 & 14.7
%O2 0.3 & 0.2
HC (ppm) 33 & 25
CO (%) 0.01 & 0.03
NO (ppm) 1115 & 735 max 825 & 764

CO2 is relatively low comparing to a very good engine, EFFICIENT AND COMPLETE COMBUSTION (15.2 TO MAX 15.6).

O2 is high and CO is very low indicates lean mixture. Low CO may also leads to low catalyst converter efficiency. Air leak past the air metering stage?
