WHAT IS A TUNE-UP?

The nature of an engine "tune-up" has changed considerably over the years, but the basics of how a gasoline engine works has not. Clean gas and air needs to be driven to the vehicle's cylinders where combustion initiated by a spark plug creates the power necessary to move a heavy vehicle. Clogged fuel injectors, dirty air and fuel filters, and corroded spark plugs can all decrease engine performance and contribute to decreased gas mileage and performance. That's why we examine your vehicle's air filter when you stop in, and why we recommend that you follow manufacturers' recommendations for replacing such key components as fuel filters, PCV (Positive Crankcase Ventilation) valves, and spark plugs when they are no longer working at maximum efficiency.

TIME FOR A TUNE-UP?

It may be time for a "tune-up" if you notice one or more of the conditions below when starting or driving your vehicle:

  • a decrease in gas mileage
  • a noticeable loss in power
  • your engine running "rough" or stalling when at a stop
  • engine "knocking" when accelerating or running-on after the ignition is turned off
  • your "Check Engine" or "Service Engine" light remaining on after initial start

COURTESY TIRE SUGGESTIONS

A standard tune-up, or spark plug replacement, done at the suggested maintenance interval will make an engine easier to start, improve fuel economy, lower emissions and restore lost power.

Another (often overlooked) service designed to help your vehicle's engine run properly is the cleaning of fuel injectors and the fuel intake system. When dirt and deposits collect on fuel injectors, the amount of fuel delivered to the engine is restricted, leading to deterioration in performance and responsiveness. At Courtesy Tire Inc, our trained technicians can perform a Fuel System Cleaning that will remove these deposits and help your vehicle maximize its performance and gas mileage capabilities. Regular maintenance of your vehicle's fuel ignition system is the key to reliability, fuel efficiency, and effective engine performance.

From fixing a fuel system problem when it occurs to helping you prevent one from happening in the future, the technicians at Courtesy Tire are there to keep your engine "tuned-up" and ready to go.
