Failed Ontario Emissions Test......
Well I took my '95 Blazer to get "E-tested today"...and I failed, which sucks. The truck idles rough and sometimes wants to die (has been running better lately), but I thought what the heck i'll bring it in for the test and see how she goes, well it didn't go too great. I just changed the plugs in the Truck on saturday....Here are my readings, and information that anyone would have would REALLY appreciated....Readings:
Highway RPM test
HC PPM- Limit-50, Reading- 415 FAIL
CO%- Limit-0.28, Reading- 1.29 FAIL
NO PPM- Limit 696, Reading- 19 PASS
RPM-2011 VALID
Dilution-15.4 VALID
Curb Idle Test
HC PPM- Limit- 200, Reading- 119 PASS
CO%- Limit- 1.00, Reading- 0.87
NO PPM- N/A, N/A
RPM 1131 VALID
Dilution-14.9 VALID
Idle test went great (which is surprising?)...but the higher RPM test didn't go as planned lol. I am not too sure what the two reading that I failed even mean, some information there would help. I'm really thinking it's the Cat, and i'm likely going to be buying one tomorrow....any other recomondations?? Also, how do you TEST the Oxygen Sensors?? Any help?

You might be right with the cat, but I'd also be looking for a vacuum leak. Your HC at idle is on the high side, passable but high.

Alright, i'll look into that. I'm gonna buy the Cat tomorrow, and put 'er on...then do another test and see how she goes.

i had the same problem with my s10 .. checked for a vacum leak and had none. so i replace my plugs and wires andre did thethe timing and it came threw with flying colors. also if there is a line at the emissions station dont let your car just idle at normal rpm keep the rpm up so that co2 doesnt build up in your cat...

I actually drive to the testing station in second gear just to make sure that my engine and exhaust are hot when I get there.

I do what Chevylover does(I do it on allmy cars that need emission testing) I take a little detour on the highwayon my way to get tested.

That's all you did??? The truck had been sitting for awhile, so i'm figuring it sounds like a cat problem. As for the idling problem, i'm going to be getting new wires also...maybe I should get some of those tomorrow two and slap them on while i'm at it.

Someone from Yahoo answers told me that it could be the Intake Gasket....which I really hope it isn't. They said to check 1-02 Sensor, 2- Map Sensor, 3- Intake Gasket.....I'm still thinking the cat more than any of those, since I have no check engine light on at all.
