Yes, I am a happy camper now, having identified the problem.
For the first time, since I laid hands on this car, it is running as it was meant to run.

Learned from this thread... Sounds like with the m103 you have to replace the IAC and Mechanical MAF sensor to get an old one "back in shape.". With the m104 all that stuff is integrated (including TPS) into an ETA which is $800 refurbished. The new IAC was $120 for OEM after careful shopping, and $35 for a refurbed " fleabay" MAF. Carbon trace was redone it looks like. Supposedly the m104 is a nicer riding engine, and less finicky though.

Most certainly beats the high cost of the ETA!
Now the even more recent models, I believe the ETA is controlled entirely electronically. Meaning there is no mechanical parts between the accelerator and the ETA.
Sure hope they have good wiring and not ECO junk, wouldn't want to be in a car with a mind of it's own.
