Routine engine tune-ups can bring power back to your Century. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Buick, you can rest assured you’re investing in your Century’s long-term engine performance.

Buick Century Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 Buick Century. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your Century'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 Century. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Century'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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

1991 Buick Century Engine Tune-Up Q&A

  • Will it hurt my Buick Century to drive with old spark plugs? 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 Buick’s recommendations.
  • What does a puddle underneath my Buick Century mean? Don't ignore puddles of fluid under your Buick Century. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • What do hard starts and stops do to my Century 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.
