How do I fix the misfiring issue in my Audi A2?

My Audi A2 has been misfiring, causing it to jerk and lose power. I've tried replacing the spark plugs and ignition coils, but the problem persists. Any suggestions on how to fix this issue?

Have you checked the fuel injectors? They could be clogged or malfunctioning, causing the misfiring. Try cleaning or replacing them.

Another possible cause could be a faulty fuel pump. It may not be providing enough fuel to the engine, resulting in the misfiring. Consider getting it checked or replaced.

Check the air filter and replace it if necessary. A dirty or clogged air filter can affect the air-fuel mixture and cause misfiring.
