How can I troubleshoot a misfiring engine in my Audi 80?

I have been experiencing a misfiring engine in my Audi 80 and I'm not sure how to fix it. The engine seems to lose power and stutter at random times. What could be causing this issue and how can I troubleshoot it?

First, check for any faulty spark plugs or ignition coils. These can often cause a misfiring engine. Next, inspect the fuel injectors and make sure they are not clogged. If those components are functioning properly, it could be an issue with the fuel pump or a vacuum leak. I would recommend taking your car to a trusted mechanic for further diagnostics.

You may also want to check the air filter and make sure it is clean. A dirty air filter can restrict airflow and cause a misfiring engine. Additionally, check for any oil leaks as these can also lead to engine misfires. If you are comfortable with DIY repairs, I would recommend consulting a repair manual for your specific model of Audi 80 for further guidance.
