Enhance GMC Jimmy Performance with a Tune-Up

Is your engine overdue for a tune-up? 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 1984 GMC Jimmy. Periodic tune-ups can bring more power back to your Jimmy’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by GMC for your vehicle’s tune-up schedule, you can rest assured you’re investing in your Jimmy’s long-term engine performance.

Routine Engine Tune-Up Service for Your GMC Jimmy

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1984 GMC Jimmy. 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*. Another service option pays special attention to the filters in your Jimmy. 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 Jimmy's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your Jimmy 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.

1984 GMC Jimmy Engine Tune-Up Q&A

  • When should GMC Jimmy 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 GMC’s recommendations.
  • What does a puddle underneath my GMC Jimmy mean? Don't ignore puddles of fluid under your GMC Jimmy. 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.
  • Are hard starts and stops bad for my GMC Jimmy 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.
