Routine Engine Tune-Up Service for Your 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 first is the standard Firestone Tune-Up. 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 Grand Prix's filters, specifically replacing the air filter and fuel 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 Grand Prix's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your Grand Prix's mileage and maintenance history can uniquely impact its tune-up needs.

1986 Pontiac Grand Prix Engine Tune-Up Q&A

  • Will it hurt my Pontiac Grand Prix to drive with old spark plugs? 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 do I do if I see a pool of liquid under my Pontiac Grand Prix? 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.
  • What do hard starts and stops do to my Grand Prix 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.
