What happens if my Lexus SC400 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 Lexus’s recommendations.

What does a puddle underneath my Lexus SC400 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 Lexus SC400 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.

How often should I clean my Lexus SC400 fuel injectors?

Tune Into Your Lexus SC400

Is it tune-up time? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you drive a 1993 Lexus SC400. Routine engine tune-ups can bring power back to your SC400. 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 follow the guidelines specified by Lexus for your vehicle’s tune-up schedule, you invest in your SC400's long-term health and engine performance.

Engine Tune-Up for Lexus SC400

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1993 Lexus SC400. 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 SC400. 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 SC400's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your SC400's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
