I took the car into an "emission specialist" shop to get a diagnosis done. The guy quoted $60 to $120 for the diag., then whatever is wrong needs to be fixed, and then a retest is necessary. He asked me how much I was willing to spend,before he had to call me for authorization. I told him $200 is the limit. I called him 3 hours later, the car had passed, and the bill was $170 plus tax ($80 for diagnosis, $55 for combustion flush, $35 for emission test)

Here are the passed test results:

ASM 2525
HC PPM limit:50, reading:37, result:pass
CO% limit .28 reading:.14 result:pass
NO ppm Limit:548, reading:46, result:pass
RPM 1395 result:valid
Dilution: 15.0, result valid

Curb idle
HC PPM limit:200, reading:38, result:pass
CO% limit 1.00 reading:.08 result:pass
NO ppm Limit:N/A, reading:N/A, result:N/A,
RPM 661 result:valid
Dilution: 15.0, result valid

Very sweet! I am good to go for another 2 years.

If anybody in the Toronto area wants the shop name/address, private message me.
