1991 Infiniti M30 Engine Tune-Ups & Maintenance

Tune-Ups to Help Your Infiniti M30 Run Better

Is it tune-up time? 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 Infiniti M30’s engine to last for a long time. Routine engine tune-ups can bring power back to your M30. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Infiniti for your vehicle’s tune-up schedule, you invest in your M30's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Infiniti M30

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 Infiniti M30. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your M30's filters, specifically replacing the air filter and fuel 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 M30’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your M30'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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

1991 Infiniti M30 Engine Tune-Up Q&A

  • When should Infiniti M30 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 do I do if I see a pool of liquid under my Infiniti M30? Don't ignore puddles of fluid under your Infiniti M30. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • Are hard starts and stops bad for my Infiniti M30 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.
