What could be causing my Audi 80's engine to stall?

I have noticed that my Audi 80's engine has been stalling frequently, even though it has been serviced recently. What could be the possible causes of this issue?

Firstly, check your spark plugs and ignition coils for any signs of wear or damage. If they are worn out or faulty, they can cause your engine to misfire and stall. Also, make sure your fuel filter is not clogged, as this can restrict fuel flow to the engine. If necessary, replace it to improve your car's performance.

Another potential cause could be a malfunctioning mass airflow sensor. This sensor measures the amount of air entering the engine, and if it is faulty or dirty, it can cause your engine to run too lean or too rich, resulting in stalling. You can try cleaning it first, but if it doesn't improve, you may need to replace it.
