Need more information, do you have a copy of the emission test stating what failed? Is the car stock, or has it been modified? High mileage?

Without more information I can give you some general guidance. Do a tune up and check to see if the catalytic converter is in good shape. A new cat can work wonders when trying to pass a smog check.

Is it failing because the readiness monitors are not set? Or won't the car communicate with DMV's equipment? Either way, visit your local auto parts store and have them scan the computer. Most stores will do it for free. Let us know what they tell you. HTH. -Jim
