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

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 I do if I see a pool of liquid under my Mercury 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.

What do hard starts and stops do to my 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 often should I clean my Mercury Grand Marquis fuel injectors?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune Into Your Mercury Grand Marquis

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, particularly if you want to keep your 2007 Mercury Grand Marquis in tip-top shape. Periodic tune-ups can bring more power back to your Grand Marquis’s engine. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Mercury for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your Grand Marquis’s engine running smoother, longer.

Engine Tune-Up for Mercury Grand Marquis

The Firestone Complete Auto Care location in your community offers several Mercury Grand Marquis engine tune-up services. The first 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*. Another service option pays special attention to the filters in your Grand Marquis. Specifically, we replace the fuel filter and air filter. 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. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Grand Marquis: 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
