I took my civic to get emissions done and here are the results

25/25 Test Reading----------Allowed
HC ppm----402--------------147 Fail
CO %------2.03-------------0.82 Fail
NOx ppm---1413------------1072 Fail
RPM--------2024------------3000 Max
CO+CO2----15.08-----------6.00 Min

50/15 Test Reading---------Allowed
HC ppm----364--------------152 Fail
CO %------1.40-------------0.85 Fail
NOx ppm---1453------------1186 Fail
RPM--------1860-----------3000 Max

Everything is stock
no engine mods.
