The term tune-up was coined when Henry Ford was working on his first automobile prototype. This first ignition system was very simple; one ignition coil for one spark plug, so four spark plugs would require four ignition 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. When all the coils were adjusted properly, they all buzzed at the same level - they were in tune. Todays distributor systems have done away with Fords configuration, but some drivers still associate poor running quality with the need to be in tune. Todays automobiles do not require old-fashioned tune-ups, but the term is now associated with the replacement of spark plugs and any performance or rough idle problem that related to engine operation.
