My area began emission testing last year. The car passed with flying
colors. Yesterday it passed again, but the results were very different
this year....mainly the CO%.
The standard is 1.20: High RPM last year was 0.01, this year 1.08. Low
RPM was up from 0.03 to 0.13.
The HC was a bit different too:
standard is 220: last year at High RPM the reading was 45 and 47 at low
RPM. This year 17 at High and 100 at Low
The other test results are similar to last years results. This
emissions testing is a new ballgame for me, so I'm at a loss to know
what these results are pointing to?
Not enough information. How was the car checked? Thee are two types (maybe
more) methods of testing depending on the year of the car. New ones you
just plug in the computer, older ones need a probe in the exhaust so the
converter will give a different reading depending on how hot it is.
