So, an input to the ECU is causing the ECU to lean out the mixture.
Most likely source is the air-flow position sensor.

I understand that the sensor in question is no longer available. What does one do?

Tiny, I would love to know where to get them.
Bosch part # 437 224 035 I have not found a source and certainly the Houston area dealers say they are no longer available. Please share with us your source.

According to this, they have been out of production for 3 years
http://www.sg-motorsports.com/AFS%20Pot%20write-up.htm Sounds like a junkyard hunt.
