Emissions Results Help
Hey guy's I'm a little lost with my smog check results.
98 Civic Ex
15 mph @ 1906rpm
CO2:15.4
O2 0.2
HC: 108 (Max: 66) FAIL
CO: 0.45 (Max: 0.57)
NO: 904 (Max: 487) FAIL
25 mph @ 2017 rpm
CO2: 15.5
O2: 0.0
HC: 45 (Max: 49) CLOSE
CO: .25 (Max: 0.55)
NO: 150 (Max: 774)
Now what would cause me to only fail the 15 mph portion, especially the NO results. Any help would be great. Thanks
