CA testing has two tests - assuming that you get the 'standard' smog
test. Every year a small percentage of what CA thinks are 'high
polluters' get randomly selected to have a dynamometer test which is
more rigorous.

Anyway, the standards for the standard smog are (This is for a 1988
vanagon - standards vary by year of manufacturer)

2500 RPM test maximum allowable:

HC PPM    180
CO %        1.0

Idle RPM maximum allowable

HC PPM    120
CO %        1.0
