Dec 17, 2013 A car tune-up is a type of preventive maintenance performed on a vehicle to ensure it continues to perform well. A tune-up is typically regularly scheduled - once a year is a very soft rule of thumb - and offers the chance for you to get all of the preventive maintenance your car needs at that time. Every repair shop determines what their particular meaning of a 'tune-up' consists of. What parts are replaced and what types of tests are done. One shop may consider a 'tune-up' as throwing in a set of spark plugs and parking it on the lot, while the next may replace spark plugs and other ignition components. Feb 27, 2015 Do Tune Ups for your car really still exist? Learn the myth about the 'Tune Up' and other car parts that have become extinct on this week's Ask the Auto Man video from Brian Bowersock at West.

Mar 02, 2018  Car tune up explained and if your car really needs one or not, myth busted with Scotty Kilmer. Older cars actually needed to be tuned up, but newer cars don't really need it. When you get car tune-ups based on your vehicle manufacturer's recommendations, you're investing in the long-term health of your car, saving you time and money. The Firestone Triple Promise. We promise that the tune-up services we perform at all Firestone Complete Auto. At its simplest, a tune-up is a type of routine maintenance to keep your car performing correctly. Regular tune-ups can extend the life of a vehicle and help ensure it is operating at its full performance potential. Typically, when to do a tune-up is included in the regular maintenance section of owner’s manuals. Many vehicles require an annual tune-up.

The word 'Tune Up' is probably the most misused and misunderstood Automotive term. According to the Merriam-Webster's dictionary under the term 'Tune-up' it says: 'general adjustment to insure operation at peak efficiency'

Before electronics came into the picture the term 'tune-up' was applied to the maintenance operation of replacing the spark plugs, distributor points, inspecting or replacing the cap and rotor and possibly replacing the fuel and air filters. There were many adjustments to be done on these cars; point gap, ignition timing and idle mixture and dwell.
This was a preventative maintenance operation that usually needed to be done about every 12,000 - 20,000 miles.

TODAY'S CARS
Distributors are now gone and even spark plug wires are missing from many applications. Forget those adjustments, the onboard computer handles fuel mixture, timing and idle speed control. On many of the newer cars, just spark plugs, fuel and air filters and PCV valve remain of the items that we used to consider part of a 'tune up'. Someday the spark plugs may disappear also.

Because the word 'tune up' can mean so many different things the manufactures don't list tune ups in their maintenance schedules. They list the items individually at specific miles or duration of time.

Due to the electronics and newer technologies the recommended mileage between 'tune-ups' or spark plug replacement has gone up to 30,000, or 60,000 and even 100,000 miles! This means that a $250 tune-up now, is cheaper than the 2 or 3 tune-ups in the same amount of mileage that were done for $100 25 years ago. Especially when you compare what $100 was worth then.

Every repair shop determines what their particular meaning of a 'tune-up' consists of. What parts are replaced and what types of tests are done. One shop may consider a 'tune-up' as throwing in a set of spark plugs and parking it on the lot, while the next may replace spark plugs and other ignition components, fuel and air filters, PCV valve and include testing to verify the electronic engine management system (if equipped) is doing its job.

If you request a tune-up, always ask what is being done for your 'tune-up' before comparing prices and don't expect a 'tune-up' to cure your performance problems. A 'tune-up' is a maintenance procedure and if it makes your car run better, you waited too long for the service. Performance problems on today's cars are usually caused by something that is not normally replaced during a maintenance tune-up.

Best Option
The best option is to not ask for a tune up, check your owner's manual for a guideline on spark plug replacement intervals. If they are due, replace them and use original equipment style spark plugs for best performance. If you do much city driving, extended idling, towing or high speed driving, reduce that recommended mileage by at least 10 - 15%.
Fuel filters, distributor caps and rotors and PCV valves should be replaced every 30,000 to 50,000 miles. Spark plug wires should be replaced every 60,000 miles.
Many new cars do not have distributor caps or spark plug wires. On some vehicles, fuel filters are part of the fuel pump and are only changed when they plug up and ruin the fuel pump.
If your car is misfiring and you don't know if the spark plugs were replaced at the last recommended interval it might be a good idea to have it done. Use the above guide for the other components.

A 30, 60 or 90 thousand mile service is not a 'tune-up', it may include tune up items but will also include many other services.
If you are wanting the scheduled services, ask for a price and breakdown on the scheduled service. (such as a 60,000 mile service) Asking for a 60,000 mile tune-up may not get you what is needed.

A Tune-up does not usually fix problems with a way a car is running.
If your car is running bad, don't expect a tune up to necessarily fix it. Computer's control the fuel and timing and perform all of the adjustments. Many of the performance problems are caused by a malfunctioning sensor, vacuum leaks or other failed components.
If the spark plugs or fuel filter are overdue, get them replaced to see if it helps, but if they're not, have a qualified technician with the correct testing equipment for your car diagnose the running problem.

Origin of the term 'Tuneup'
Many early car's magneto ignition systems were very simple with one ignition coil for each spark plug. Each coil needed to be adjusted to provide the same spark intensity for better idle and acceleration. As these coils worked, they made a buzzing sound. When adjusted properly, they all buzzed in tune, thus coining the term 'tune-up'.

Tune-up intervals vary from one vehicle to another. Most older vehicles with non-electronic ignitions should be tuned every 10,000 to 12,000 miles or every year, whichever comes first. Newer cars with electronic ignition and fuel injection systems are scheduled to go from 25,000 miles to as many as 100,000 miles without needing a major tune-up.

Refer to your owner’s manual for recommended tune-up intervals, but be aware that even if it says that the vehicle doesn’t require scheduled tune-ups very often, it’s in your best interest to check periodically that your vehicle is working at peak efficiency. If you do a lot of stop-and-go driving or pull heavy loads (like a camper or boat), your ignition system may need to be tuned more often. Here are a couple of symptoms that tell you that your electronic ignition system may need to be tuned or adjusted:

What Does A Full Auto Tune Up Consist Of

• The car stalls a lot. The spark plugs may be fouled or worn, the gap between the spark plug electrodes may need adjusting, or an electronic sensing device may need to be adjusted.

• The engine is running roughly when idling or when you accelerate. Chances are the vehicle needs a tune-up.

• The car gets harder to start. The problem can be in the starting system (for example, a weak battery), in the fuel system (for example, a weak fuel pump), or in the ignition system, or can be due to a faulty electronic component, such as the electronic control unit (ECU).
