2 readings that stand out to me are stepper motor 13 and idle speed 824.
They are both on the low side, the idle should be 875 and the stepper at 21.

You may need to screw in the idle screw on the throttle body. Get the engine up to temp and disconnect the iacv(stepper motor). Check the idle, it should be 850rpm. If not adjust the screw, 1/4 turn at a time.
Plug in the iacv again and observe how the idle changes it should settle at 875, you may have to repeat this as the iacv sorts itself out
