Why does my Audi 80's engine feel sluggish?

I've noticed that my Audi 80's engine has been feeling slow and unresponsive lately. What could be causing this issue and how can I improve my car's performance?

There are a few potential reasons why your Audi's engine may be feeling sluggish. One possibility could be a clogged air filter, which can restrict air flow and decrease engine power. Another possibility could be an issue with your fuel system, such as a dirty fuel filter or a problem with your fuel injectors. In either case, it would be a good idea to have a mechanic take a look and perform a tune-up if necessary.
