When should Audi 90 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 Audi’s recommendations.

What do I do if I see a pool of liquid under my Audi 90?

Don't ignore puddles of fluid under your Audi 90. 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.

What do hard starts and stops do to my 90 engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Tune-Ups to Help Your Audi 90 Run Better

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it might be time to change your ways, especially if you want your 1989 Audi 90’s engine to last for a long time. Regular engine tune-ups can optimize your 90’s power on the road. 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 Audi for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your 90’s engine running smoother, longer.

Engine Tune-Up for Audi 90

The Firestone Complete Auto Care location in your community offers several Audi 90 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*. The second service focuses on your 90's filters, specifically replacing the air filter and fuel 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 90. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your 90's mileage and maintenance history can uniquely impact its tune-up 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.

Where Should I Go for My Audi 90 Tune-Up?

If you’re looking for 1989 90 engine tune-up services, head to Firestone Complete Auto Care.
