What Exactly is An Auto Tune Up?

The cars of today have come a long way in terms of performance, reliability and technological improvements. The term tune-up has undergone a drastic change over the course of automotive history. However, the term is still being used in 2019, especially when it comes to dealing with older cars.  A tune-up a type of auto repair service that is performed to make an engine run at its peak performance. There isn’t an exact definition as to what a tune-up may entail, but many would concur that it usually involves a change of spark plugs and minor adjustments to the engine.

In newer cars, there isn’t much adjusting to do as functions like ignition timing and fuel mixture ratios are in fact controlled by a computer. Even though you check on the base timing and emission function to see if they are within the fixed parameters of what the manufacturer recommends, there simply isn’t much that can be tuned. Yet auto enthusiasts of today still believe in the boost of performance that a tune-up is supposedly able to deliver.

The term tune-up usually comes up because someone is experiencing some kind of problem with their car. For instance, your car might not be registering the kind of miles per gallon as it normally does or when excessive engine knocking is apparent. This is when a more basic form of tune-ups are performed to get the car performing as it should. A new set of spark plugs could be all the tune-up a car needs. New spark plugs can help improve on fuel economy, restore some lost power and even reduce engine knocking that you may have been experiencing. However, tune-ups of today aren’t going to solve all of your problems. If these problems remain even after a tune-up, then it’s safe to say that the problem lies elsewhere and would require a more detailed inspection.
