Quite often, a customer will call and ask for a “Tune-Up” believing that this is the “fix” for a poor running engine, a check engine light, etc. Although in some cases, replacing the spark plugs may repair a poor running engine, it quite often makes no difference simply because it is not the cause of the problem at hand. If you have an engine running problem, we would be happy to help, but we recommend beginning with some basic engine diagnosis. Although, the term “Tune-Up” no longer means what it used to; it is still a term that we use to refer to ignition maintenance related services (replacement of spark plugs, etc.). Most vehicle owner’s manuals specify the appropriate interval for replacement of the spark plugs, etc. and we believe that the best course of action is to follow these recommendations called “Recommended Maintenance” or “Scheduled Maintenance”.
