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

I've been experiencing occasional misfires in my Audi 80 and I'm not sure what the root cause might be. Can someone give me some insight on what to look for and how to fix it?

One of the most common causes of an engine misfire in an Audi 80 is a faulty ignition coil. You may want to check that and replace it if needed.

Another potential cause could be clogged fuel injectors. Try using a fuel injector cleaner and see if that resolves the issue. If not, it may be time to replace them.

Another thing to consider is a vacuum leak. Try using a smoke tester to pinpoint any potential leaks and seal them accordingly.
