Will it hurt my Jeep Wrangler to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Jeep Wrangler mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my Jeep Wrangler engine than others?

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.

How frequently do I need to get my Jeep Wrangler fuel injectors cleaned?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune-Ups to Help Your Jeep Wrangler Run Better

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 2004 Jeep Wrangler’s engine to last for a long time. Regular engine tune-ups can optimize your Wrangler’s power on the road. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Jeep, you invest in your Wrangler's long-term health and engine performance.

Engine Tune-Up for Jeep Wrangler

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2004 Jeep Wrangler. 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 Wrangler'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 Wrangler. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Wrangler'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 Should I Go for My Jeep Wrangler Tune-Up?

Come to Firestone Complete Auto Care for your next 2004 Wrangler engine tune-up. Follow Jeep's recommended maintenance schedule or book an appointment as soon as you notice one of the following: stalling or shaky idling when you’re stopped, diminished fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
