Will it hurt my GMC Jimmy 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 GMC Jimmy 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 GMC Jimmy engine than others?

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.

How often should I clean my GMC Jimmy fuel injectors?

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.

Enhance GMC Jimmy Performance with a Tune-Up

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, now is the time to work on that habit, especially if you drive a 1999 GMC Jimmy. Routine engine tune-ups can bring power back to your Jimmy. They're designed to help your engine start easier and run more 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 GMC, you’re taking vital steps toward keeping your Jimmy’s engine running smoother, longer.

Engine Tune-Up for GMC Jimmy

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1999 GMC Jimmy. 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 Jimmy. Specifically, we replace the fuel filter and air filter. 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 Jimmy's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your Jimmy can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! 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 GMC Jimmy Tune-Up?

If you’re looking for 1999 Jimmy engine tune-up services, head to Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use GMC’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
