Why is my Audi 80's engine producing less power than usual?

I recently noticed that my Audi 80 has been struggling to accelerate and the engine feels weaker than usual. What could be causing this and how can I improve its performance?

It's possible that your air filter is dirty and needs to be replaced. A restricted air flow can greatly affect your engine's performance. Try changing the air filter first and see if that helps.

Another common issue could be a clogged fuel filter. This can greatly reduce the amount of fuel reaching the engine and result in decreased power. Consider getting the fuel filter replaced if it hasn't been changed in a while.
