1991 Pontiac Grand Prix Engine Tune-Ups & Maintenance

Enhance Pontiac Grand Prix Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you drive a 1991 Pontiac Grand Prix. Regular engine tune-ups can optimize your Grand Prix’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Pontiac's recommendations, you can rest assured you’re investing in your Grand Prix’s long-term engine performance.

Engine Tune-Up for Pontiac Grand Prix

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Pontiac Grand Prix 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 Grand Prix. Specifically, we replace the fuel filter and air 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 Grand Prix. 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 Grand Prix 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

1991 Pontiac Grand Prix Engine Tune-Up Q&A

  • When should Pontiac Grand Prix spark plugs be replaced? 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 Pontiac’s recommendations.
  • What do I do if I see a pool of liquid under my Pontiac Grand Prix? 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 hard starts and stops bad for my Pontiac Grand Prix 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.
