UPDATE: '93 240 failed emmisions test in Ontario

I passed !!! :-)

Thanks to James Sweet for suggesting to use the product to clean valves & injectors.

OK, now the facts:

In first test,HC was at 83 (linit is 66), CO was at 0.40 (limit is

In today's test I got 66 for HC ( a 20.4% reduction from last test), CO at 0.23 (a 42.5% reduction) and NO at 451 (a 50% reduction).

As you can see, my HC is at 66 and the limit is 66!!! So what do you suggest? I'm OK for now, but if HC increases by just one, I'll fail the test in two years.

Should I get the technician at the Volvo dealer to manually clean valves & injectors or should I just give it another treatment or two?

Btw, I gave it two treatments. First one was for injectors only. The improvement was marginal, ~ 5-10%. But the second treatment was for the valves. injectors, etc. That made a h*ll of a difference. The car drives 100% better. Accelerration is unbelievable.

Thanks.

Btw, I used the Canadian Tire brand of cleaners.
