What Does a Tune-Up Consist Of?

Regular tune-ups are necessary to keep your engine running smoothly and to prevent costly repairs later on. While most tune-up services have evolved to fit the modern engine, emissions, and fuel delivery system, the goals have not changed. Today, we will go over some of the most common components that get serviced and/or replaced during a tune-up service.

Spark Plug

Spark plugs are key to helping the engine get started. The electrodes in these components will slowly deteriorate over time. The distance between the two electrodes will increase, making it difficult for the voltage to jump from one to the other. Furthermore, dust and dirt deposits cling onto the component itself. Generally, spark plugs can last anywhere between 45,000 miles to 100,000 miles depending on the type of spark plugs used and the driving conditions they are operated on. A replacement will be determined upon inspection.

Filters & Valves

Tune-ups involve adjusting and replacing the parts that impact the combustion system, which means your technicians should not miss the filters in your vehicle (fuel, air, etc.). If they are clogged or dirty, we can replace them without a problem. Furthermore, the PCV valve is also another component inspected for wear and tear.

Oxygen Sensor

Oxygen sensors are key to perfecting the engine’s air-to-fuel ratio.  The sensor measures the amount of unburned oxygen in the vehicle’s exhaust and sends the measurement to the car’s computer.  The computer then adjusts the mixture to minimize emissions.  When an oxygen sensor stops working, your car will run inefficiently for a while until the sensor is replaced.


A significant portion of tune-ups includes cleaning the intake and fuel system. If left alone, things will build up and clog the systems.  Most manufacturers recommend cleaning these systems approximately every 50,000 miles.
