What Does Union Weber Autocare Do During a Smog Check?

Next, we will inspect your car or truck's gas cap, ignition timing, exhaust gas recirculation system, fuel, and evaporative system.
Finally, we will perform a Tailpipe Emissions Inspection which measures the type and quantity of any pollutant emitted from your vehicle's tailpipe.
