What happens if my Audi 90 spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

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.

Are hard starts and stops bad for my Audi 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.

How often should I clean my Audi 90 fuel injectors?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Enhance Audi 90 Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 1991 Audi 90. Routine engine tune-ups can bring power back to your 90. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Audi's recommendations, you can rest assured you’re investing in your 90’s long-term engine performance.

Routine Engine Tune-Up Service for Your Audi 90

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Audi 90 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*. Another service option pays special attention to the filters in your 90. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your 90’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your 90 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

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

If you’re looking for 1991 90 engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Audi, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
