What happens if my Mercury Grand Marquis spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Mercury’s recommendations.

What do hard starts and stops do to my Grand Marquis engine?

Routine Engine Tune-Up Service for Your Mercury Grand Marquis

The Firestone Complete Auto Care location in your community offers several Mercury Grand Marquis engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your Grand Marquis. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Grand Marquis's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your Grand Marquis's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
