THE M4CHIN3

This code has been popping up intermittently the last two weeks or so.
I know the code is for the IACV but provides no more specifics then that.
Here is also 2 samples of Freeze frame data most recently. No other codes have EVER popped up on it either.
I have "burped" the radiator twice, both times with bubbles coming up.
I have replaced the radiator cap with a brand new one.
I have tested the IACV according to the procedures outlined by Haynes manual.
(removing the IACV connector with the engine warmed up and in parked.)
It passed that test.
I have removed the valve itself and cleaned it out,but it wasn't really dirty.
I have cleaned out the air filter as well.
No coolant leaks or fluid of any kind.

Im thinking its either the ECU has gone bad or The idle needs to be set right witch I have the instructions to do so set by Honda;or even just burped a little more.

Thoughts?

Adjust the idle speed as per service manual instructions and then go from there.
