What is the cause of poor acceleration in a Audi 80?

I have been experiencing sluggish acceleration in my Audi 80 and was wondering what could be the cause. It seems to be struggling to reach high speeds and takes longer than usual to accelerate.

The most common cause of poor acceleration in an Audi 80 is a dirty air filter. Make sure to regularly clean or replace the air filter to ensure optimal performance.

Another possible cause could be a faulty oxygen sensor. This can cause the engine to run rich, resulting in reduced acceleration. It is recommended to get the sensor checked and replaced if necessary.
