What Exactly is a Tune Up?


McKonly's Garage Blog

It seems like a simple question, "What's a tune up?" Unfortunately, it is difficult to pinpoint an easy answer. The term has a long history and originally referred to specific auto maintenance tasks that were necessary in order to make old cars and trucks continue to run correctly. However, as vehicles have become more advanced the term has evolved, and now the services completed during a tune up varies from vehicle to vehicle. Tune ups are generally performed in between major scheduled services, when a car just doesn't seem to be running quite as well as it should.

Replace Spark Plugs & Wires

One part of the original tune up that has not changed is replacing dirty or corroded spark plugs and spark plug wires. Spark plugs usually have a long road life, but they do become worn out over time. Most need to be replaced every 30,000 miles or so.

Vacuum Check

During a tune up a technician may perform a check on vacuum lines to detect air leaks and check for exhaust system restrictions.

Filter Replacement

Another general service performed during a tune up may be the replacement of the fuel filter, air filter and cabin air filter. New filters will help ensure a smooth running, happy & healthy car.

Belt & Hose Inspection

The tune up mechanic will check out all belts and hoses, including those that are part of the cooling system. They will also make sure it is not time for a timing belt replacement.

Fuel Injector Cleaning Service

Modern vehicles are fuel injected and throughout the life of the injectors they may collect dirt and grime, which may reduce the amount of fuel that they can feed to the engine. A cleaning will remove the buildup and restore proper fuel delivery to the engine.

Check for Fault Codes

Many problems may not present themselves with noticeable symptoms, however your vehicle's computer system will be able tell if something is wrong. An auto technician can hook your vehicle up and find out if there are any issues that are being detected by your car's vast sensor system.
