Stumbling After Cold Start

[dzidaV8]

I have checked the log, you are running a little rich with BLMs around 120, and the moment you tap the throttle it gets momentarily lean from what I can see. Check your fuel pressure and have a look at the spark plugs.
If you still have stock injectors it's a good idea to check them or replace them anyway to D3 type injectors. Stock ones tend to finish their life after those 30 years.

EDIT: I read on other topics that your car is far from stock... I'd say to give it more AE on low temperatures in: "AE Delta TPS Pulse Width Factor Vs. Temp. ".
And work on the tune, log shows rich everywhere.
