Emissions retest another failure - ZR-1 Net Registry Forums

03-10-2009

Just to add some more info.

New plugs
New coils
New plug wires
Cats are new

Theoretically, this car should have no issues passing emissions. A couple of things in talking to Darryl.

AZ still uses the IM240 testing, which Oregon had and recently got rid of. Having a stock ZR-1 pass on them was getting tougher as the car was never designed to pass that kind of test, and they have also been lowering the passing limits here.

Second, if you have a jack rabbit operating the car on the dyno, it will fail.

Darryl is going to try the stock PROM and see where we wind up and go from there.
