For your car to get its best gas mileage and engine performance, it needs clean fuel injectors, air filters and fuel filters. Plus, its spark plugs need to be in good condition.

If you notice one of these issues below, it’s time to have us run diagnostics on your vehicle:    
— Decreased gas mileage
— Compromised power
— "Rough" running engine or stalling when stopped
— Engine "knocking" during acceleration, or running on after the ignition is turned off
— "Check engine" light or "service engine soon" light remains on after initial start

This is why we examine your vehicle’s air filter when you stop in, and it’s why we recommend you follow manufacturer recommendations for replacing key components like filters and spark plugs when they’re past their prime.
