Check for vacuum leaks on the engine and the idle air control valve (IAC). The IAC is responsible for maintaining the engine idle speed. When you turn the AC on, there is an added load on the engine which requires the IAC to increase the idle speed. If it doesn't, the added load will bog the engine down.
