What are the common causes of a rough idle in an Audi 80?

I've noticed that my Audi 80 has been idling roughly lately. What could be causing this issue?

One of the most common causes of rough idling in an Audi 80 is a dirty or clogged fuel injector. It's important to regularly clean or replace your fuel injectors to ensure smooth idle and overall engine performance.

Another possible cause of rough idle is a malfunctioning oxygen sensor. This sensor measures the air-fuel ratio in your engine and if it's not working properly, it can lead to a rough idle. Have your oxygen sensor checked and replaced if necessary.
