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

I have noticed my Audi 80 engine often stutters and shakes at idle. What could be causing this issue and how can I troubleshoot it?

The most common cause of engine misfires in Audi 80 models is faulty ignition coils.

I recommend checking for any clogged fuel injectors or a malfunctioning fuel pump as these can also cause engine misfires in the Audi 80.

In my experience, a dirty or faulty mass airflow sensor can also contribute to engine misfires in Audi 80s.
