Why is my Audi 80's engine stalling at idle?

I recently noticed that my Audi 80's engine has been stalling at idle. This only happens sometimes, but it's becoming more frequent. Does anyone have any ideas what could be causing this issue?

Hi Mark, it sounds like you might have a dirty or faulty idle air control valve. This is a common issue in older Audi 80's. I recommend cleaning or replacing the valve to see if that solves the problem. Also, make sure your spark plugs and air filter are clean and in good condition. Hope this helps!
