Tune ups past and present
When a customer tells me that they need a tune up, my first question is, "Why?". It may seem a little rude at first, but it's because I have had some bad experiences because I didn't ask. Most people don't start looking into getting a tune up until something is wrong with their vehicle. In most cases, a tune up won't fix the problem and the customer is angry because they spent money for it. So by asking, I can actually help my customer save money.
In most cases, a check engine light does not mean that you need a tune up. This is a common misconception. At times, there can be misfires which are caused by bad spark plugs. When that happens, the vehicle will run poorly as well as causing a check engine light. However, 90% of check engine lights are for other reasons. So to just assume a tune up is wrong about 90% of the time.
Tune ups should be done for maintenance before a problem surfaces. The definition of tune up can be (and usually is) greatly debated.
