I have had my 92 Accord tested for Ontario Drive Clean and Failed on NO test.After $350 out of my pocket that those gangsters claimed to do a diagnostics ($150) and clean the EGR ports ($200) it passed the test. But I have a question that bothers me so much whether others had similar problems. Let's see the results first.
First Test : ASM2525 Curb Idle HC ppm 27 18 CO % 0.01 0 NO ppm 783 (failed because the acceptable limit is 467)
Second Test ASM2525 Curb idle HC ppm 44 124 CO% 0.03 0.05 NO ppm 123
As you see it shows an improved NO reading but everything else went up. Since two consequent tests in the same facility gives different results obviously the condition of the car whether it was hot or just driven into the test facility might effect the results. I am guessing here since I do not know better. Anybody can enlighten me what else might be different. I think we, the consumers as drivers, are shafted again by our government.
