Why does my Audi 80 have a rough idle at startup?

I recently bought a used Audi 80 and noticed that it has a rough idle at startup. The engine seems to shake and sputter for a few seconds before smoothing out. What could be causing this issue and how can I fix it?

The most common reason for a rough idle at startup in an Audi 80 is a dirty throttle body. Make sure to clean the throttle body using a specialized cleaner to improve the engine's idle.

Sometimes, the issue can be with the ignition coils. Check if they are faulty or damaged and replace them if needed.
