1990 Infiniti Q45 Engine Tune-Ups & Maintenance

Tune-Ups to Help Your Infiniti Q45 Run Better

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 1990 Infiniti Q45’s engine to last for a long time. Periodic tune-ups can bring more power back to your Q45’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 Infiniti, you invest in your Q45's long-term health and engine performance.

Engine Tune-Up for Infiniti Q45

The Firestone Complete Auto Care location in your community offers several Infiniti Q45 engine tune-up services. The standard Firestone Tune-Up is one service option. 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 Q45's filters, specifically replacing the air filter and fuel filter. 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 Q45. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Q45'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.

Common Engine Tune-Up Q&A For 1990 Infiniti Q45s

  • Will it hurt my Infiniti Q45 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 does a puddle underneath my Infiniti Q45 mean? Don't ignore puddles of fluid under your Infiniti Q45. 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.
  • What do hard starts and stops do to my Q45 engine? You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.
