because a/c takes more power to run it. try cleaning throttle plate on both sides and iac hole with choke cleaner see if that takes care of it

I had already done that a few days ago but makes no effect. When the A / C is off smoothly all is well.

There should be an idle up for the A/C normally should be a vacuum switch that bypasses the throttle plate with the a/C on to idle up and help maintain a smooth idle

could be in need of a valve adjustment as I hear a lot of clacking goin on in video or sticky valves which I doubt or worn valve guides. due to mileage it could be any of those

Without a / c on, idle and then accelerating a bit and then releasing the accelerator:

IAC has any effect the control valve when idle when the A / C is turned on?

everything yu are showing on vacuum gauges are normal have you even tried adjusting valves or still questioning what we have suggested. I have no further comments.

I managed to repair the unstable idling.
The thermistor a / c each as active time on and off the compressor ?. Mine does about every 10 seconds.
