What happens if my Mercedes-Benz 500SEC spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

Is it tune-up time?

Engine Tune-Up for Mercedes-Benz 500SEC

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1993 Mercedes-Benz 500SEC. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 500SEC. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your 500SEC. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your 500SEC: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
