Idle issue

My car idles really weird when I have the air conditioner or defrost on, the rpms move between 400-600 and last night I had the radio up, lights on, and the defrost on low fan and the car stalled. I just got a brand new idle air control valve. The car idles fine without the AC/defrost on. When the AC or the defrost is on it also holds rpms longer when I push the clutch in to change gears. Any help is much appreciated

check your voltage output on the altanetor. Your drawing alot of juice at once.

You can also try upgrading your terminals.
Bigger terminals>Better connection>More secure
Had this problem with my stereo..

Talking about autozone.. I bought these terminals from there, $16 I think for the + and like $6 for the - . Made a huge difference. I can turn on ac + everything else and still hold a steady 13.8 volts. (Note I also have HID's, 2 amps and complete stereo setup.)
