Why is my Audi 80 losing power after driving for a few miles?

I recently noticed that my Audi 80 starts to lose power after driving for a few miles. The acceleration becomes slower and the engine starts to sound different. What could be causing this issue?

It is possible that your car's spark plugs need to be replaced. Over time, they can wear out and cause the engine to lose power. I recommend getting them checked by a mechanic.

Another potential cause could be a clogged air filter. A dirty air filter can restrict airflow to the engine, resulting in reduced power. Try changing the air filter and see if that improves the performance.
