How do I troubleshoot engine misfires in my Audi?

I've recently noticed my Audi experiencing engine misfires, causing a rough idling and decreased performance. How can I diagnose and fix this issue?

First, check your spark plugs and replace them if necessary. Then, clean the fuel injectors and check the fuel filter for any clogs or debris.

Make sure to also inspect the ignition coils and wires for any damage or wear. These can often be the cause of engine misfires in Audis.
