The KAM circuit for the PCM and the a/c is on the same circuit.
If the PCM does not have memory voltage it will loose the settings every time you turn the key off.
You might want to check the fuses in the engine compartment for a blown fuse for this circuit.
Of course it could have another problem too, such as a faulty idle air control valve.

look at spark plug 6 see if it is foul out with oil. when you first start you car up and it smokes blue you have leaking valve seals and stop up oil return holes.if all is good .check 6 injector make sure its getting power.

Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
