What are common causes of stalling in a Audi 80?

My Audi 80 has been stalling frequently and I'm not sure what could be causing it. Any ideas on what could be the problem and how to fix it?

One common cause of stalling in Audi 80s is a faulty idle air control valve. This valve controls the amount of air entering the engine when the car is idling and can cause the engine to stall if it is not functioning properly. It is recommended to have this valve checked and replaced if necessary by a mechanic.

Another potential cause of stalling could be a clogged fuel filter. This can restrict the amount of fuel flowing to the engine, causing it to stall. To fix this, you can try replacing the fuel filter yourself or take it to a mechanic for professional help.
