This blog was started to help you understand the California State Smog Check program and to offer information about specific emissions related problems. I will answer questions and post remarks and helpful hints you can use to get your vehicle ready for your next Bi-annual smog check.

(Disclaimer) This blog is not intended to offer a diagnosis or recommend a specific repair. It is always best to have your vehicle diagnosed and repaired at an emissions repair station certified to do so by the Ca. State Smog Program.
