"I'd highly recommended them. They're very good at doing work with ignition problems and they're very knowledgeable. I like the fact that they were able to diagnose the problem fairly quickly and come up with a solution. They're a specialty shop and they have diagnostic equipment that most of the other places didn't have. They fixed an ignition problem that I had and I had them do the smog certification. They're very knowledgeable." -Scott H.

A: Diamond Certified smog test shops use top-quality brands like Banks Power, Dynomax, Bully Dog, Airaid and Hooker Headers.

A: Smog test shops typically offer two types of smog tests: the two-speed idle test, which measures the amount of pollutants released when the vehicle is idling, and the acceleration simulation mode (ASM) test, which measures the vehicle's exhaust emissions when accelerating. Both tests measure the amount of hydrocarbons, carbon monoxide, and nitrogen oxides in the exhaust, and results are compared against the vehicle's emissions standards. Depending on the state, the smog test shop may also offer an evaporative emissions test, which tests for hydrocarbons in the evaporative system, or an On-Board Diagnostics test, which tests the vehicle's computer system.
