A tune-up restores engine performance that has degraded gradually over time, often without the driver noticing the progressive loss. Raytown drivers who have not performed scheduled maintenance on their vehicles typically notice the improvement in throttle response, fuel economy, and smooth idle that a proper tune-up produces. The components involved in a modern tune-up differ from the older definition. On today\'s vehicles, a tune-up centers on spark plug replacement, air filter replacement, fuel filter service where applicable, PCV valve inspection, inspection of ignition components, and review of any diagnostic codes stored in the engine management system. Spark plugs fire thousands of times per minute. Over time, the electrode gap widens as the electrode material erodes, requiring a higher voltage to fire the plug. This causes the ignition system to work harder and may produce misfires that the driver experiences as roughness under load. New spark plugs restore the specified gap and firing voltage.
