How do I fix a misfiring engine in my Audi 80?

Recently, my Audi 80 has been experiencing a misfiring engine, causing it to run rough and consume more fuel than usual. How can I fix this issue and improve my car's performance?

First, I would recommend checking your spark plugs and ignition coils. If they are worn out or faulty, they could be causing the misfiring. Replace them if necessary.

You may also want to check the mass airflow sensor and clean it if it's dirty. A dirty sensor can contribute to a misfiring engine.
