See if you can find a used AIC valve. You said it idles fine with the A/C on. I had an AIC Valve with low mileage do the same thing once. Something to do with the aplied voltage from the ECU to control the valve vane opening. Your A/C send cause the ECU to open the valve futher for the extra compressor load.
