When should Mitsubishi Diamante spark plugs be replaced?

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 does a puddle underneath my Mitsubishi Diamante mean?

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 some driving habits better for my Mitsubishi Diamante engine than others?

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.

Tune Into Your Mitsubishi Diamante

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you drive a 1993 Mitsubishi Diamante. Periodic tune-ups can bring more power back to your Diamante’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 get routine engine tune-ups based on Mitsubishi's recommendations, you invest in your Diamante's long-term health and engine performance.

Engine Tune-Up for Mitsubishi Diamante

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mitsubishi Diamante 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*. A second service option replaces the air and fuel filter in your Diamante. 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 Diamante. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Diamante'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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Where Should I Go for My Mitsubishi Diamante Tune-Up?

Schedule your next 1993 Diamante engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Mitsubishi’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: 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.
