Leave cracker alone for the time being.
“Cruise-control” off throttle is frequently caused by too much base running airflow.
Getting your base running airflow values dialed in can help resolve a number of issues.
Start there before you dive down the other rabbit holes.
Google “RussK idle config” to find the resources to help you easily graph idle desired air vs. ECT

I would get your fueling close first before you begin dialing in base running airflow.
Remember that it is an iterative process

Looks like someone fat-fingered those values, but they are limited to 1600-2800rpm at 64 mph.
The other photo you posted shows IAC position at 2 at hot idle, meaning the IAC is nearly completely closed. Usually those counts are around 30-60 or so at hot idle. Hard to make conclusions from a photo of a datalog, but I still think you’ll get the “cruise control” sorted by dialing in your base running airflow
