What causes the 1990 Audi 80 to have poor acceleration?

I have a 1990 Audi 80 and I've noticed that it struggles with acceleration. What could be causing this issue?

It's possible that your spark plugs are dirty or worn out, causing the engine to struggle with acceleration. Try replacing them and see if that improves your car's performance.

Another common issue with older Audi 80s is a clogged air filter. It's a simple and inexpensive fix, but can make a big difference in your car's acceleration.
