What happens if my Mitsubishi Montero Sport spark plugs fail?

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 Mitsubishi’s recommendations.

What does a puddle underneath my Mitsubishi Montero Sport mean?

What do hard starts and stops do to my Montero Sport 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.

Enhance Mitsubishi Montero Sport Performance with a Tune-Up

Is your engine overdue for a tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you drive a 2003 Mitsubishi Montero Sport. Regular engine tune-ups can optimize your Montero Sport’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 follow the guidelines specified by Mitsubishi for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your Montero Sport’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mitsubishi Montero Sport

The Firestone Complete Auto Care location in your community offers several Mitsubishi Montero Sport engine tune-up services. The standard Firestone Tune-Up is one service option. 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 Montero Sport. 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 Montero Sport'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 Montero Sport can determine what kind of service it 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.

Where to Get a Tune-Up for Your Mitsubishi Montero Sport
