What are the most common causes of engine misfiring in an Audi 80?

I was noticing my Audi 80 engine misfiring and was wondering what could be causing it. I want to make sure I address the issue before it becomes a bigger problem.

The most common causes of engine misfiring in an Audi 80 are faulty spark plugs, a clogged fuel filter, or a faulty ignition coil. Make sure to inspect and replace these parts as needed to fix the issue.

Another possible cause of engine misfiring in an Audi 80 could be a dirty or faulty mass air flow sensor. Try cleaning it with MAF sensor cleaner or replace it if necessary.

If you have recently replaced your spark plugs and are still experiencing engine misfiring, it could be due to a faulty fuel injector. Have all of your fuel injectors tested and replace any that are not functioning properly.
