i have a 1996 nissan 300zx and i always have a hard time passing the california emissions smog test

i know my car inside and out, i've become very familiar with it

i wonder if there are other poeple who also have problems passing their smoke test in the emissions part of the smog test

when i got to the smog test only stations i fail and then i pass after i fix it

hi,

we have a 1993 300zx 2+2. we recently moved to denver, and after having passed the emmissions test in memphis for years and years, we failed the colorado test. basically we have too much (just over the limit) of co and hc in the exhaust - while the car is driving. at idle, the emissions are clean. i suspect the problem is likely the o2 sensors and/or the cats. any ideas?
