What causes the engine hesitation in my Audi 80?

I have noticed that when I start my Audi 80, there is a slight hesitation or delay in the engine when I press the accelerator. What could be causing this and how can I fix it?

One possible cause of engine hesitation in an Audi 80 is a dirty or clogged air filter. This can restrict the flow of air to the engine, leading to hesitation. To resolve this issue, try replacing the air filter or having it cleaned.
