When should Isuzu I-Mark 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 Isuzu’s recommendations.

What does a puddle underneath my Isuzu I-Mark mean?

What do hard starts and stops do to my I-Mark 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.

Tune-Ups to Help Your Isuzu I-Mark Run Better

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 1985 Isuzu I-Mark’s engine to last for a long time. Regular engine tune-ups can optimize your I-Mark’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 get routine engine tune-ups based on Isuzu's recommendations, you can rest assured you’re investing in your I-Mark’s long-term engine performance.

Engine Tune-Up for Isuzu I-Mark

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Isuzu I-Mark engine tune-up services. One option 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*. A second service option replaces the air and fuel filter in your I-Mark. 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 I-Mark. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your I-Mark'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.
