What happens if my Hyundai Sonata 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 Hyundai’s recommendations.

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.

Are hard starts and stops bad for my Hyundai Sonata 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 Hyundai Sonata Performance with a Tune-Up

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 1994 Hyundai Sonata’s engine to last for a long time. Routine engine tune-ups can bring power back to your Sonata. Tune-ups help your engine start smoothly and run 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. The standard Firestone Tune-Up is one service option. 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. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Sonata’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 Sonata'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. 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 Hyundai Sonata Tune-Up?

Come to Firestone Complete Auto Care for your next 1994 Sonata engine tune-up. Not sure when you’re due for a tune-up? Use Hyundai’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: shaking while the engine is idling, poor fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
