Passed Smog
Just did my smog test and she passed, only low point was the HC (PPM)
Max AVG MEAS 135 73 120 Did a complete tune up, cap/rotor, plugs, filters and oil change. did a high speed run down the highway prior to taking it in, tech said it was passing unburnt fuel causing the high reading, possibly my Cat starting to go bad? Last edited by Malo83; 06-22-2017 at 04:28 PM. |

Re: Passed Smog
Bi-annual? Let's hope you don't have to go thru that routine every 6 months. That could get expensive.

Re: Passed Smog
Always a sigh of relief, mine barely passed this year my NOX was about 10ppm under the max, running too lean I think. When I got it back home I turned the screws out some more.

Re: Passed Smog
I only had one square body ever pass emissions and it was as close as I could get to failing. I eventually just started plating them where there was no emissions
