If you think it will be boarderline just before the test it might not hurt to pass the guy a 20 tucked in with your paperwork (grease payment).

As long as your Vette is all stock and well maintained, there won't be a problem.

If the plugs, wires, air filter, oil and o2 sensors haven't been changed in awhile, you might be in for a surprise. Good luck though.

6 speed or auto? I had one in a SD Co zip code and had much higher NOx limits (1995 6-spd).

also is your car a cali cert or a federal emission package

The NOx Max numbers change from test to test. When I did a pre test inspection(Failed) the NOx Max numbers the first time were 692 ppm(15 mph) and 711 ppm(25 mph) , the second time I did a pre test(Failed)
the NOx Max numbers were 484 ppm(15 mph) and 541 ppm(25 mph).

car is a 6 speed...I'll look at the label to see if it was originally a Cal certified car.

your numbers look pretty good, how many miles?

it was 88k miles for that last test. The EGR valve itself got old and failed and it was actually a retest. The first time the HC's were even cleaner, but NOx went to a 1000 on one of the sections. easy fix, luckily.

still can't explain why your NOx standard is lower. My car has the YF5 Ca emissions option.

OK, I looked at the emissions label under the hood, and it calls out..California Certified.

Really strange how there seems to be differant standards?
