About This Service
Fixing an out-of-tune engine can give you better gas mileage — by an average of 4% or 16¢ per gallon.1
Today's engines are highly advanced and difficult to troubleshoot. That's why the experts at Tire & Service Network locations use sophisticated engine diagnostic equipment and vehicle computer data to pinpoint hidden problems and worn parts. Depending on the age and model of your vehicle, your engine tune-up service includes:
- A thorough inspection of your entire engine and its mechanisms
- Replacement of faulty or worn electronic engine components such as oxygen sensors and electronic control module components
- Replacement of faulty or worn spark plugs, air filters, and fuel filters
- Adjustment of your vehicle's idle and timing
- Adjustment of the clutch (on vehicles equipped with a manual transmission)
Why are tune-ups important for my vehicle?
Normal vehicle usage causes various parts of your engine to lose their efficiency because of under-the-hood temperature and vibration.
- Regular tune-ups help maintain vehicle safety and performance by ensuring that worn or faulty parts are replaced promptly
- Tune-ups can help you achieve maximum fuel efficiency and vehicle performance
