Idle fluctuating - only with A/C on
I just charged the A/C in the car (04 MSM, FMII) and now the idle fluctuates greatly, between 1000 to 2000 rpm, but only with the A/C on. It settles down to normal with the A/C off.
The AC Clutch Idle Speed Target is set to 200 across the board for all temperatures. Any ideas?
I am new to ECU tuning, and this car, and was reluctant to start changing settings without a little more guidance.

I tried adjusting both P and I-term to no avail. P-term went from 150 to 50, I-term from 20-10. It would return to normal idle while the ECU was applying the new value, but would start to oscillate again as soon as the A/C clutch engaged.
Another strange part is that two out of the ten or so times that I restarted the car, it didn't oscillate with the A/C on.
