1993 Sentra 1.6 rough idle

Hi, we are back, we put in new injectors, new fuel filter, new distributer cap and rotor, new plugs and plug wires and finally another MAF and the car was running super great, now several eeks later it is running very rough at idle and almost quits with the AC running. When we rev it up it appears to be running smooth, Where do we go from here

you might try just turning the idle up a little. There should be a little screw at the end of the throttle cable.
