How do I diagnose and fix a recurring issue with the engine of my Audi A2?

I have been experiencing a recurring issue with the engine of my Audi A2. It seems to be misfiring and losing power randomly. What could be causing this and how can I fix it?

It sounds like your A2 may have a faulty ignition coil. This can cause intermittent misfires and loss of power. You should have it checked and replaced by a certified mechanic.

Another common issue with the A2 engine is clogged fuel injectors. This can also cause misfires and loss of power. Try using a fuel injector cleaner solution to see if it helps improve the performance of your engine.

If the issue persists, it could be a problem with the oxygen sensor. This sensor is responsible for measuring the air-fuel ratio in the engine and a faulty sensor can cause engine issues. Have it checked and replaced if necessary.
