What happens if my Lexus SC400 spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my SC400?

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 Lexus SC400 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 Lexus SC400 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.

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 Lexus SC400 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 might be time to change your ways, especially if you drive a 1994 Lexus SC400. Periodic tune-ups can bring more power back to your SC400’s engine. 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 Lexus, you invest in your SC400's long-term health and engine performance.

Engine Tune-Up for Lexus SC400

The Firestone Complete Auto Care location in your community offers several Lexus SC400 engine tune-up services. 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 SC400's filters, specifically replacing the air filter and fuel 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 SC400’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your SC400 can determine what kind of service it 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 Lexus SC400 Tune-Up?

Schedule your next 1994 SC400 engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Lexus’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, engine knocking, or an illuminated check engine light.
