The term TUNE-UP was coined back when Henry Ford was working on his first ignition system prototype for the automobile.
Cars' ignition system was very simple at that time; one ignition coils for one spark plug, so if there was four spark plugs, there would be four coils. These coils needed to be adjusted to provide the same spark intensity for better idle and acceleration. As these coils worked they made a buzzing sound, so when he adjusted them properly they all buzzed same; therefore there were in tune and that is how the TUNE - UP was born.
Once the ignition distributor was developed the term tune-up had no meaning, but the consumers who was the use to hearing this term around the garage, automatically associated poor engine running quality with the need to be in tune. So the term TUNE - UP stuck and was associated with the replacement of spark plugs and engine performance problem.
Today's automobiles do not require tune-ups. Automobiles manufacturers have set forth in there recommended maintenance schedules, intervals for replacing spark plugs, PCV valves, fuel filters, timing belts, etc, while recommending that other items related to engine operation be checked for proper operation or adjustment such as idle speed, timing and emission control related devises.
When and only when the maintenance has been performed, should the performance problem be addressed to correct any given set of problems. If an operating or performance problem is still present after the maintenance has been performed, and engine analysis would then be required. Therefore the term tune-up indicates the need for routine maintenance and should not be associated with poor performance.
If your fine European Import car experiences any operating or performance problems between maintenance intervals, that specific problem should be addressed by performing an engine analysis by a professional car repair technician to isolate that particular problem.
Henry Ford's time was possible to make a tuna up at any garage with a little knowledge.
