It could be the A/C clutch.

Ha, I have this exact same problem.

Measure out your alternator. If he doesn’t give enough on idle with the A/C on that could be the source

yep and the fun part there is(atleast in my case) while that range of hondas the M/T’s had the IAC on the backside of the intake while the A/T or in my case CVT i had a A6 head and the IAC was mounted underneath the intake..

[EricTheCarGuy]

The pressures may be normal but there may still be a problem with the compressor, if you see a lot of orange dust around the clutch this could indicate that it’s slipping.
