Why does the engine of my Audi 80 sputter when I accelerate?

I have recently noticed that my Audi 80 seems to sputter or make a strange noise when I accelerate quickly. Can anyone explain why this might be happening? It only seems to occur when I am going at higher speeds.

This could be due to a clogged air filter, which can cause a lack of air flow and lead to sputtering or rough acceleration. I would suggest checking and replacing the air filter if necessary.

Another potential cause could be a faulty spark plug. If the spark plug is worn or dirty, it can affect engine performance and cause sputtering. It may be worth checking and replacing the spark plugs.
