What causes misfire in an Audi 80?

I have recently noticed a misfire in my Audi 80 while driving. It seems to happen randomly and I'm not sure what the cause could be. Any insight would be greatly appreciated.

One common cause of misfire in an Audi 80 is a faulty ignition coil. It's important to have this checked and replaced if necessary to prevent further damage to your engine.

Another possible cause could be a dirty or clogged fuel injector. Try using a fuel injector cleaner to see if that resolves the issue. If not, it may need to be replaced.
