Why is my Audi 80 having trouble accelerating?

I've noticed that my Audi 80 has been struggling to pick up speed, especially on highways. I usually have to press the accelerator harder to get it to go faster. What could be causing this issue?

It's possible that your fuel filter is clogged and needs to be replaced. A dirty filter can restrict the flow of fuel to the engine, causing decreased acceleration.

Another potential problem could be a faulty mass air flow sensor. This sensor measures the amount of air entering the engine and helps regulate fuel delivery. If it is malfunctioning, it can cause poor acceleration.
