So, positive results from this 1 sensor but it still stalls.
Could be the plug or a single wire in the plug. Could be loose. Could be corroded. If you do something and this something makes the symptoms better, but still fails, you should at least be on the right track.
I had a cam sensor issue a few years back and read on a Porsche forum that guy had cam sensors go bad but turned out it was corrosion on the plugs connection. The pins. Not the sensors.
