Your car’s engine is made up of hundreds of complex components working together to ensure that your vehicle starts and runs properly. Over time, however, these components can wear out, resulting in a loss of performance and fuel economy. Here you’ll learn what a tune-up is and tips to help you know when its time for a tune-up.
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.
It may be time for a tune-up if you notice any of these:
- 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-up
