and its "idle", not idol

idle at 800 RPM when A/c not on and when A/c on it drop down to like 300 RPM and sometime die out at stop sign..

raising idle screw wont help.

i think the clutch in the A/C compressor is stuck?

or load sensor...

what you guys input?

Well I doubt the compressor clutch is stuck, otherwise there wouldn't be any drop in rpm, it would just be a constant drag.

I also don't think it's the ELD (electronic load detector), as the A/C is a parasitic drag on the belt system, the electronic part of it is not what causes the RPMs to drop. A possibility would be the compressor is starting to sieze up, which is causing the belt system to work harder to turn it. I would say raise the idle and see if the drop follows consistantly with it. So, if you raise the idle to 1000 RPM, is should drop to 500 RPM when kicked on. That would at least give a little better idea of what's going on.
