How to troubleshoot an engine misfiring on an Audi 80?

I've been experiencing engine misfiring on my Audi 80 lately and I'm not sure what could be the cause. What are some steps I can take to troubleshoot this issue?

First, check the spark plugs and wires to make sure they aren't worn or damaged. If they are, replace them. Next, check the fuel injectors for clogs and clean or replace them as necessary. Finally, check the ignition coil to see if it's functioning properly.

Another possible cause of engine misfiring could be a faulty oxygen sensor. Have it checked and replaced if necessary. Additionally, check the air filter to make sure it's clean and replace it if needed.
