What causes the engine of an Audi 80 to stall while idling?

I have recently bought a used Audi 80 and noticed that the engine tends to stall while idling. I have changed the spark plugs and checked the air intake, but the issue persists. Does anyone have any insights on what could be causing this?

There are a few potential causes for an engine stalling while idling in an Audi 80. The first thing I would check is the fuel injector, as it could be clogged or faulty. You could also have a vacuum leak that is affecting the idle air control valve. Make sure to also check the ignition control module and the fuel pump.

I had a similar issue with my Audi 80 and it turned out to be a faulty idle air control valve. It is responsible for regulating the engine's idle speed and can malfunction over time. I would suggest checking it and possibly replacing it if necessary.
