    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.

    That's how Ontario got the garages to agree to hosting the tests, by
    promising they've eventually get their $100,000 investment back by milking
    drivers for repair money.

    This is one reason McGuinty backed off his intention to repeal the smog
    test: The garages and related associations screamd blue murder about losing

    It is *CRITICAL* to the results. The engine must be fully warm, and the cat
    MUST be hotter than hot to work most efficiently.

    There is a "conditioning" procedure that MUST be followed for older cars
    to reliably pass, especially since Ontario has been screwing the limits
    down each year in order to lop off the lowest 10%.

    See my own results here:

    All kinds of things.

    1) Condition/calibration of test equipment
    2) Heat of catalytic converter
    3) Ambient temperature
    4) Random test glitches.

    Paul Coninx, a well-know opponent of such I/M programs as Drive Clean, has
    chronicled the saga of a Cavalier (or Sunfire, I forget which) that was
    taken to eleven different test stations as an experimnet. This car failed
    about half the time and passed about half the time, with some wildly
    different results. Nothing at all was done to the car in between.

    No kidding.

  3. Using a slide hammer to pull the EGR plugs in the intake manifold, shooting
    some spray into the ports, poking around a bit with some drill bits, and
    hammering in some fresh plugs.

    He made an election promise to cancel this program and not to raise taxes.
    I, an idiot who should know better not to trust politicians, fell for it.
    I also wanted to see a fresh face in Ontario. But what a naive optimist I was.
    Never again. No promise whatsoever can drag me to the polls for the rest
    of my life. I know its is not honda related but I had to take this out of my
    By the way what does "cleaning the EGR ports" mean ? I checked the EGR
    valve and they did not remove it at all. Two years ago Canadian Tire charged me
    over $100 to "decarbonize" and passed the test conditionally. I checked the
    web and did not find any procedures but just some sprays into the carburetor
    which is not applicable for fuel injection systems.
