How can I fix the idle problems in my Audi 80?

I am experiencing irregular idle speed and stalling in my Audi 80. It tends to happen when the engine is cold and it gets better as the car warms up. How can I troubleshoot and fix this issue?

First, make sure your air filter is clean and the idle valve is functioning properly. Then, check for any vacuum leaks in the hoses and connections. A common cause of idle problems in Audi 80s is a faulty MAF sensor, so it's also worth inspecting that.
