How do I troubleshoot my Audi's engine misfire?

I'm experiencing a rough idle and noticeable loss of power while driving my Audi. What steps can I take to pinpoint the cause of the engine misfire and fix it?

First, start by checking your spark plugs and ignition coils for any signs of wear or damage. If they look fine, move on to checking your fuel injectors and air filter. These components can also contribute to engine misfires.

Another common cause of engine misfires in Audis is a faulty oxygen sensor. These sensors are responsible for monitoring the air-to-fuel ratio in the engine, and if they're not functioning properly, it can lead to a misfire. Consider getting your oxygen sensor replaced.
