What is causing a delay in my Audi 80's acceleration?

I've noticed that my Audi 80 is taking longer than usual to accelerate when I step on the gas pedal. The engine seems to struggle before eventually catching up. What could be the cause of this issue?

It's possible that your fuel filter is clogged and needs to be replaced. This can cause a decrease in engine performance, leading to a delay in acceleration.

Another potential issue could be a malfunctioning oxygen sensor. This can affect the fuel-air ratio and cause a delay in acceleration.

Have you checked your spark plugs? Worn out or dirty spark plugs can affect the engine's efficiency and result in a delay in acceleration.
