Back in 2001 year, almost exactly two years ago, I posted my '91 Carat's smog test results after it had a complete tune-up. I was a bit amazed at the results. Today it got its biennial emission test Interestingly the Carat 2 years later runs cleaner at 2500 and idles cleaner (lower HC) but emits more carbon monoxide at 2500 but less at idle...possibly due to the bottle of Techron additive I put in at fill-up prior to the test? 2500 rpm MAX allowable Average Measured Result '01 '03 '01 '03 HC ppm 0180 0020 0024 0021 PASS PASS CO % 1.00 00.10 0.00 0.10 PASS PASS CO2 14.6 10.7 O2 .2 .00 RPM 2527 2649 IDLE RPM MAX allowable Average Measured Result '01 '03 '01 '03 HC ppm 0120 0030 0023 0017 PASS PASS CO % 1.00 00.10 0.03 0.00 PASS PASS CO2 14.3 9.00 O2 0.00 0.00 RPM 0890 0823 NOTE: O2 sensor has never been replaced Carat miles: 109K in 2001; 130K in 2003. Emissions testing has gone up $15-$20 with no discernable difference in the procedure for vehicles without an OBD-II.
