Will it hurt my Mercury Grand Marquis to drive with old spark plugs?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my Grand Marquis?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Mercury Grand Marquis engine?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

How frequently do the fuel injectors in my Mercury Grand Marquis need to be cleaned?

Mercury Grand Marquis Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1994 Mercury Grand Marquis. One option is the standard Firestone Tune-Up. 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. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Grand Marquis’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Grand Marquis's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
