How to troublehsoot poor acceleration in an Audi 80

I've been experiencing slow acceleration in my Audi 80 lately, and it's becoming quite frustrating. Can anyone provide some advice on what might be causing this issue and how to resolve it?

One common cause of poor acceleration in an Audi 80 is a clogged fuel filter. Try replacing the filter or cleaning it if possible.

Another possible issue could be a malfunctioning oxygen sensor. Have a mechanic run a diagnostic to check for any error codes related to the sensor.
