What happens if my Infiniti QX4 spark plugs fail?

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 QX4?

Don't ignore puddles of fluid under your Infiniti QX4. 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 QX4 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.

Enhance Infiniti QX4 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, particularly if you want to keep your 2002 Infiniti QX4 in tip-top shape. Periodic tune-ups can bring more power back to your QX4’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Infiniti's recommendations, you’re taking vital steps toward keeping your QX4’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Infiniti QX4

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2002 Infiniti QX4. One option 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*. A second service option replaces the air and fuel filter in your QX4. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your QX4'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 QX4'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.

Where to Get a Infiniti QX4 Tune-Up

Come to Firestone Complete Auto Care for your next 2002 QX4 engine tune-up. Consult your vehicle’s recommended service schedule from Infiniti, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
