Will it hurt my Hyundai Sonata 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 Hyundai Sonata mean?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my Sonata engine?

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 frequently do the fuel injectors in my Hyundai Sonata need to be 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.

Enhance Hyundai Sonata Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 1991 Hyundai Sonata’s engine to last for a long time. Regular engine tune-ups can optimize your Sonata’s power on the road. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Hyundai's recommendations, you invest in your Sonata's long-term health and engine performance.

Engine Tune-Up for Hyundai Sonata

The Firestone Complete Auto Care location in your community offers several Hyundai Sonata engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your Sonata. 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 Sonata'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 Sonata 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! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
