2003 Honda Odyssey Idle Problem [EGR or IAC problem?]

2003 Honda Odyssey 225K Miles.
Idling Problem.

First and foremost; Apologies where apologies due, the lighting condition is quite poor. As diagnostic aid I've put some annotations as guides.

What do you think replace/clean EGR, replace/clean IAC? know the engine come with EGR but no sure about IAC. Or may be the problem lies somewhere else entirely different [with the car]. Please comment and let me know what you guys think.

Thanks
Pete
