Another possibility, discounted though because no A/C problems were mentioned, is that the A/C compressor no longer actually engages, however the idle speed compensation circuitry, not realizing that, continues to enrich the idle. If that's the cause, of course, then pressing the "ECON" button to turn off the A/C will result in the idle becoming once again normal.
