Why does my Audi 80's engine sputter on acceleration?

I recently purchased a 1998 Audi 80 and have noticed that when I accelerate, the engine sputters and struggles to gain speed. It seems to be worse when the engine is cold. What could be causing this issue?

It could be a problem with the fuel injectors. Try to get them cleaned or replaced to see if that resolves the issue.

Check the spark plugs and wires for any signs of wear or damage. Replacing them may help improve the engine's performance.

Have you checked the air filter? A clogged air filter can cause engine sputtering and poor acceleration. Consider replacing it if it's dirty or obstructed.
