I failed California smog again. My car is an '87 900T Conv. w/5 spd. The readings are as follows:
15mph: HC 72(116 max,31 avg), CO% 0.37(0.74 max, 0.10 avg), NOX: 1028(791 max, 237 avg)
25mph: HC 49( 91 max, 20 avg), CO% .23(.62 max .09 avg), NOX: 728(730 max, 199 avg)
On the 15 MPH test My CO2% was 14.6 and my O2% was 0.6
On the 25 MPH test my CO2% was 14.7 and my O2% is 0.4
Could a tired cat be causing these high NOx readings? I am only failing one portion of the test (15 MPH NOx) but all my readings are higher than the average and my cat is 17 years old with over 160K miles.
It seems my CO2/O2 pecentages indiindicate good combustion and good engine condition and my car isn't running hot either.
