What happens if my Infiniti QX4 spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Infiniti’s recommendations.

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.

Tune Into Your Infiniti QX4

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, particularly if you want to keep your 2001 Infiniti QX4 in tip-top shape. Regular engine tune-ups can optimize your QX4’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Infiniti for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your QX4’s engine running smoother, longer.

Engine Tune-Up for Infiniti QX4

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2001 Infiniti QX4. 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*. Another service option pays special attention to the filters in your QX4. Specifically, we replace the fuel filter and air 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 QX4. 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. 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 Infiniti QX4 Tune-Up?

Come to Firestone Complete Auto Care for your next 2001 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: 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.
