How can I troubleshoot my Audi 80's engine misfiring?

I recently noticed my Audi 80's engine has been misfiring and I want to know how I can troubleshoot and fix this issue.

First, check your spark plugs and replace them if needed. This is a common cause of engine misfires. If that doesn't solve the issue, have a mechanic run a diagnostic check to determine the exact cause.

Make sure your fuel filter and air filter are clean and not clogged. Dirty filters can cause engine misfires. Also, check for any loose or damaged wires in the ignition system.
