Default Having trouble with TBA on my 99 30v..

So I have VCDS working and communicating with the car properly. I do the TBA as specified in the millions posts taht exist about this issue, and 060 seems to be the code that works cause when I do 098 it brings up voltage levels which say 4.xxx and 3.xxx and ADP.OK right next to it. With 060, you see the values start to change around, from 7 to 9 to8 than falls to 2.2 and 2.2 and the 2.6 just sits there blinking. It switches on the right from ADP RUN or something to ADP.OK pretty fast, I let it sit for 30-a min and I go to start the car.

Sounds like it fires up great, idles for two seconds than drops and garbles and dies. I've tried 3-4 times with it ending at the same 2.6 and 2.2 values, and no changes. It starts much cleaner than it did, but wont keep running...any ideas?

Mind posting an Auto-Scan? Especially with the older cars it may be a different MVB to start the TBA, to be sure you could check the factory repair manual or we could once we know the engine code and such.

I am pretty sure you can only enter 060, or 098 in terms of a TBA. I have tried both, mine 098 brings up voltage and such, 060 preforms the adaptation, always ending back at 2.6 and 2.6 ADP OK.

I tried keeping my toe pressed slightly on the gas, and after the TBA I had to give significant pressure to the accelerator to keep it running, and after holding my foot at about 3k RPM for a few seconds, the car stayed running on its own, tiny bit rough though. Almost sounds like the car is misfiring now as when I drive, if you push the gas too much the car chokes for a second.

No offense but do you want help or do you want to argue what could and could not be the case? You would really make it A LOT easier for us if you'd just post the Auto-Scan so we can double check what really has to be done here...
