Dlag;

Since you are in California, you should be aware the the Seller is responsible for smogging any car sold, not the buyer... I would go back at the person you bought it from for some compensation. If they refuse, they must refund you and take the car back. If you bought it "As-Is" with a specific written term stating that you are responsible for smog, then you forfeited your rights.

That said, the failure for the lower rpm NO test and the lower rpm HC test can be caused by too rich a fuel mixture... Also, just running the car around for 20 minutes doesn't keep the cat as hot as it needs to be for testing purposes when the results are borderline. Too much airflow will cool the Cat off... If you have a free re-test, go back after the car is warm and then keep the engine running while you wait for them to put it on the dyno. Keep your RPM's around 2500 while you are waiting. This will get the cat hotter and will increase it's efficiency during the test...

A tune-up may help with the NO and HC, as clean frest plugs, coilpacks and filters will burn more effeciently and reduce the emissions...

Good Luck!
