How can I troubleshoot my Audi A2's engine misfiring issue?

I have recently noticed that my Audi A2's engine is misfiring and I am not sure what could be causing it. I have checked the spark plugs and they seem to be functioning properly. I am worried about causing further damage and would appreciate any advice on how to troubleshoot this issue.

It's likely that the misfiring is caused by a faulty ignition coil. It's best to take your car to a mechanic to properly diagnose and replace the faulty part.

This could also be caused by a clogged fuel injector. Try using a fuel injector cleaner and see if that improves the misfiring. If not, it's best to take it to a mechanic.
