Q: Need to pass smog check
My car did not pass its smog check.
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 potential factors. I would strongly recommend having a mechanic, such as one from YourMechanic, inspect your vehicle and make the repairs needed to pass the smog test.
