Denatured Alcohol Users Give Opinion (please)
I've read loads of info about this method of passing emissions.
Who thinks these numbers could pass with this method?
Readings Allowed
HC (ppm) 475 132
CO % 3.34 0.73
NOx 127 945
Are these #'s too far off to be dropped enough to pass?
Anyone know how a bad cat effects these readings? Could a better cat help oxidize some CO into CO2?
Because my initial thought was the cat was poisoned or clogged. My O2 sensor seems to be working fine, registers a 14.7 A:F while cruising with a WB.
TIA

You can probably reduce your numbers by 1/2 with alot of alcohol but I think your is too much. I would check for air pump clutch not engaging or bad cat. How many miles on your cat? I think about 50k -60k is about the life you could expect from an aftermarket high flow, not sure on a stock.
