Re: Smog Test = GROSS POLLUTER

Well than, you guys need to keep your cars nice and warm for those tests.
Make sure your car has been running for 15-20 min before taking it to a
testing station.  Cats actually PRODUCE NO2 when they are cold and not
up to operating temperature.  

PS---Just checked my last emissions test, you are incorrect sir.  Colorado
does test for NOx on their rolling dyno tests.  Catless I pass with flying
colors.  I re-iterate that a properly tuned CIS system can pass even
the tough dyno tests.

Last test on my 80 rocco, no cat:

HC .5858 (limit 4)
CO 12.8353 (limit 30)
CO2 286.2526 (no limit it seems)
NOx 1.0757 (limit 8)

Those are all in GPM (I assume grams per million?)

Oh, and they even test the damn gas cap here....California isn't the only
state with Nazi-like emissions.
