How do I troubleshoot an engine misfire in an Audi 80?

I recently noticed my Audi 80's engine has been misfiring and causing rough idle. I'm not sure what could be causing this issue and how to fix it. Any recommendations would be greatly appreciated.

Possible causes for an engine misfire in an Audi 80 could be faulty spark plugs, ignition coils, or fuel injectors. It's best to start by checking these components and replacing them if necessary. Also, don't forget to check for any vacuum leaks in the intake system.

In some cases, an engine misfire in an Audi 80 could be caused by a malfunctioning mass airflow sensor. Try cleaning the sensor and see if that improves the engine's performance. If not, it may need to be replaced.
