I'd like some tips (additives, etc) on what I can do to ensure my car passes it's next California smog check next year, since it seems it barely passed it's last check.
It's a 99 Mazda Protege with 320k miles. It was sitting for about year when I put in a newer engine (with 94k miles) earlier this year. The smog check brought the registration up to date a few months ago. There was one category that to my untrained eye looked like it was pushing the pass limit. Wondering if the newer engine being dropped in less than a month before the test would have a big effect. Any opinions and interpretations of the results are appreciated!
15mph -- RPM = 1874, %CO2 = 15.1, %O2 = 0.1
25mph -- RPM = 1807, %CO2 = 15.1, %O2 = 0.1
15mph -- HC(PPM) = 47 [max = 64, ave = 9]
25mph -- HC(PPM) = 10 [max = 47, ave = 7]
15mph -- CO(%) = 0.22 [max = 0.55, ave = 0.02]
25mph -- CO(%) = 0.19 [max = 0.54, ave = 0.03]
15mph -- NO(PPM) = 459 [max = 477, ave = 57]
25mph -- NO(PPM) = 31 [max = 764, ave = 50]
