Q: Car won't pass smog check

asked by on

My car won't pass the smog check. What do I need to do to get it to pass?

Hi there. Your smog check is measured as to how efficiently your vehicle is burning fuel and air. Smog is reliant on many different components. Your EGR valve, vacuum, and also your catalytic converter are factored in. I would strongly recommend to have a mechanic, such as one from YourMechanic, precisely diagnose the problems your vehicle is experiencing with failing smog requirements.
