A tune-up performed by a professional technician typically involves basic services such as measuring and adjusting tire pressures, changing motor oil, and testing lights and windshield wiper blades.
Historically, a tune-up also included replacing the fuel filter, air filter, spark plugs, distributor cap, and rotor, but modern-day cars have changed significantly, and many components such as carburetors, spark plug wires, or distributor caps are no longer present. Therefore, a modern-day tune-up usually involves replacing spark plugs, changing the air filter, and cleaning the intake or fuel injectors. ๐
