That's normal- the car still thinks the AC is there so it's increasing the idle to keep the extra load of the compressor from stalling it out.
8 valvers accomplish this through a little cylindrical valve piped around the throttle body, while 16 valvers do this through the engine management (LH) computer. My 16 valve car is far more picky about idling high when I turn my fans on. You can either use it as a fast idle switch, live with it, disconnect the 8 valve idle increasing valve, or disconnect whatever wire sends the AC on signal to the ECU, although I'm too chicken to try this yet.
