How to troubleshoot a misfiring Audi engine?

I have a 2016 Audi A4 that's been experiencing engine misfires. I've already replaced the spark plugs and checked the coils, but the issue persists. What else could be causing this problem and how can I fix it?

It's possible that your fuel injectors are clogged and need to be cleaned or replaced. Dirt and debris can build up over time and cause misfires in the engine. I recommend taking your car to a professional mechanic to have them inspect and clean the injectors if needed.

Have you checked the air filter? A dirty or clogged air filter can restrict airflow to the engine and affect its performance. Try replacing the filter and see if that resolves the issue.
