What is the most common cause of engine misfire in the Audi 80?

I have noticed my Audi 80 is experiencing engine misfiring. Can anyone tell me what the most common culprit for this issue is?

The most common cause of engine misfire in an Audi 80 is a faulty ignition system. This can be caused by worn spark plugs, damaged ignition coils, or dirty fuel injectors. I would recommend checking and replacing these components if necessary.

Another common cause of engine misfire in an Audi 80 is a clogged air filter. If the filter is dirty or blocked, it can restrict the airflow to the engine and cause misfiring. I would suggest checking and replacing the air filter regularly.
