What are the common issues with the Audi 80's fuel injectors?

I recently bought an Audi 80 and noticed some issues with the fuel system. I am not sure if it's a common problem with this model or if there's something specific I should be looking for. Can someone provide some insight on the common fuel injector issues for the Audi 80?

One of the most common issues with the fuel injectors in the Audi 80 is clogging due to carbon build-up. This can lead to reduced fuel efficiency and engine misfires. To avoid this problem, make sure to regularly use a fuel injector cleaner and avoid using low-quality fuel.
