What happens if my Lexus LS400 spark plugs fail?

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 should I do if I see leaks under my LS400?

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.

What do hard starts and stops do to my LS400 engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Enhance Lexus LS400 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 drive a 1994 Lexus LS400. Regular engine tune-ups can optimize your LS400’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 take your car for regular engine tune-ups as recommended by Lexus, you can rest assured you’re investing in your LS400’s long-term engine performance.

Engine Tune-Up for Lexus LS400

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Lexus LS400 engine tune-up services. The first is the standard Firestone Tune-Up. 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 LS400's filters, specifically replacing the air filter and fuel filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your LS400. 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 LS400 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! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
