Anytime you hit the Throttle you are exiting Idle..see B0108.

That immediately transitions you to the High-Octane Spark table. Then as your Throttle decreases back to ~0 TPS, you will go back to the Base Spark in Gear. All of the Idle Airflow Parameters are active only at Idle (TPS< 1%), so you may be experiencing either a huge swing in Spark and or Fueling. I would look at the High Octane Spark table for answers.

On a side note, I keep B5920 enabled. B5934 still looks like it needs modifying. One thing I do not understand are your values in B4324, B4325, and B4329. That means your PCM will learn extremely high swings in Airflow..you want the opposite..keep those limits stock or your Idle Airflow will go nuts.

Also, you need at least stock Airflow corrections for B4301 and B4302. Without them once your cooling fans kick in your car will most likely stall from the additional load. Out of curiosity has is your battery performance(voltage)?
