    Before the 70's, a "tune-up" was an actual tune up.

    Those days, engines were mainly mechanically operated and items such as the distributor points and condensers, carburetors, engine timing, etc. needed to be periodically checked and adjusted.

    During the 70's, 80's, and maybe the early 90's, most of those items were either replaced by more modern systems and/or became computer controlled.

    So although the term tune-up still lingers within the automotive industry, today it basically means changing the spark plugs and inspecting other items such as filters, fluid levels, the condition of hoses, etc.

    Now days it's replacing the spark plugs, replacing the air filter, and cleaning the throttle body.

    A few cars still have a fuel filter.

    Now-a-days, it's usually spark plugs and ignition coils and maybe even the ignition module depending on age and miles driven and the history of your cars ignition module in general. Meaning the reliability of your OEM ignition module. Most people will go at least ten years before doing such.

    A car tune-up is a type of preventive maintenance performed on a vehicle to ensure it continues to perform well.

    It is a process of adjusting and/or renewing worn-out engine parts, usually related to ignition and fuel systems. Modern cars with computer engine management tune themselves, except for filters that get dirty, and spark plugs that wear out. If you need a major tuneup, that can include taking care of the valves and cam timing.

    back when grandpa was running the show cars had mechanical ignitions and carburettors that needed to be reset and adjusted regularly to keep the car running properly a tune up was usually changing the spark plugs points resetting the point gap checking the ignition timing and adjusting the idle mix. Since efi showed up just just do services as in change the oil and air cleaner mostly.

    For the most part unless you have an old car, it's an obsolete practice.

    Check the timing, replace the rotor and distributor cap, new spark plugs, check all the fluids.

      Platinum spark plugs are good for 100,000 or more miles
