A tune-up is a service that is performed on a vehicle to improve its performance and fuel efficiency. A tune-up typically includes a variety of maintenance and repair tasks, such as replacing the spark plugs, air filter, and fuel filter, and adjusting the ignition timing and carburetor (if applicable).
Tune-ups are typically recommended at regular intervals, as specified in the owner's manual. The recommended interval can vary depending on the make and model of the vehicle, as well as the type of driving it is used for.
If you are experiencing issues with your vehicle's performance or fuel efficiency, or if it is time for a tune-up, it is recommended that you take it to a professional mechanic or an auto repair shop that specialized in tune-up services. They will be able to diagnose and fix any issues with your vehicle, as well as perform the necessary maintenance tasks to improve its performance and fuel efficiency.
