Why does my Audi 80 constantly lose power while driving?

I have an Audi 80 and I've noticed that it's been losing power while driving, even at high speeds. It's also been making a strange noise. Any idea what the problem could be?

It sounds like your engine could be misfiring due to a faulty spark plug. I recommend getting it checked by a mechanic to avoid potential damage to your engine.

Based on your description, it's possible that your fuel filter may be clogged, causing the power loss. Consider getting it replaced to improve your engine's performance.
