What could be causing my Audi 80 to have trouble accelerating?

I've noticed that my Audi 80 is struggling to accelerate, especially when going uphill or when I need to quickly merge onto the highway. What could be causing this issue and how can I fix it?

It's possible that your fuel filter is clogged, which can restrict the flow of fuel to the engine and result in poor acceleration. I recommend replacing the fuel filter to see if that improves your acceleration.

Another common cause of poor acceleration in the Audi 80 is a dirty air filter. A dirty air filter can limit the amount of air reaching the engine, causing it to work harder and resulting in slower acceleration. Try changing your air filter and see if that makes a difference.

It's also important to check your spark plugs, as worn or dirty spark plugs can lead to weak spark and reduced engine power. Consider replacing your spark plugs and see if that improves your acceleration.
