What happens if my Ford Mustang 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.

What do I do if I see a pool of liquid under my Ford Mustang?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

Are hard starts and stops bad for my Ford Mustang engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Enhance Ford Mustang Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 1991 Ford Mustang’s engine to last for a long time. Periodic tune-ups can bring more power back to your Mustang’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Ford, you’re taking vital steps toward keeping your Mustang’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Ford Mustang

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Ford Mustang engine tune-up services. The first 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 Mustang. 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 Mustang. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Mustang: 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.

Where to Get a Ford Mustang Tune-Up

If you’re looking for 1991 Mustang engine tune-up services, head to Firestone Complete Auto Care. Follow Ford's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
