ok i just went in for an emssions and it failed yet no code issues to even consider it
HCPPm limit 66 reading 146
CO% limit 0.37 reading 0.58
NO ppmlimit 0505 reading 1537
thats at 40km/h
curb idl is
Hcppm limit 200 reading 123
CO% limit 1 reading 0.03
No ppm n/a n/a
now curb idle pass's but not the 40km
so what causes this
also this car was orginalyl outfitted for 1 02 sensor the 2nd 02 sensor was capped off as the org cat didnt have one
now when i put a brand new exhaust on it since i didnt have option for 2nd 02 sensor i capped off 02 sensor hole on the cat and when i ran it last year it over heated on the intake side of the cat turned red hot then i had to replace it and it also turned red hot
then i just bought a 2nd 02 sensor and had to find out where on the engine where gm capped off the 2nd o2 sensor plug and pluged it in but now i needed to emission it and it failed car never went on road since last year as i had anti theft on it stuck on
so is this problem the Cat? the Innova code scaner i have all it shows is the EPA flashing but rest are good
like i have brand new exhaust from front to back and 2 new o2 sensor

I had a chevy that was 16yrs old and had 380,ooomi on it and it produced 26 HC .
your excessively high readings to me say your running way too rich.
could be a diaphram torn .
if you replace the cat converter with a rich condition the vehicle will glow very bright red. that is the function of a cat to burn the unburned fuel .
could also be bad compression/plugs /wires/valves etc that would cause unburned fuel to get to the cats.
A PROPERLY RUNNING ENGINE WITH NO CAT CONVERTERS SHOULD GET MUCH LOWER READINGS THAN YOU HAVE.

oh ic well from the one garage they said it is usually the thermostat sensor that tells the cars computer that its -40 out
but i had that replaced and i installed the down stream 02 sensor and it hasnt turned red
so thats why i thinking its damage the cat since it turned red hot from jsut idlying last year
