Emissions Testing

[GipperND]

I have to do my first CA emissions testing in the next two weeks. Is there a consensus on whether it's better to test with the car in full power or not?

They won't ever reach a throttle position high enough to tip into the secondaries anyhow. Mine passes with it in either position.

Thanks for the response. My '98 Corolla barely passed last time so I'm a little nervous about the ZR-1. Fingers crossed.

The bad news....we have full emissions test here... gas cap, idle test and dyno test.

The good news.... with new injectors, plugs and no vacuum leaks - the Z passed with flying colours, AND they are eliminating vehicle tests here end 2014 (very few cars are failing) and will focus on heavy industrial vehicles only

What happens in TX if you drive to an area they dont do the sniff test? Do you need proof you live out there?

The last time my car smogged real clean was 10 years ago, but after replacing the O2 sensors, the NOx really came down this time and it runs clean again. The fuel mixture band for the formation of the fewest oxides of nitrogen is so narrow and it does require accurate 02 readings. I was surprised that the sensors foul with age more than mileage (20-30k miles on the somewhat more dirty tests).

The county the car is registered in determines the testing procedure. So, to answer your question..yes. To go to a nontesting county the car has to be registered there.
