When the compressor kicks in -the computer should raise the RPM to compensate for the additional engine/electrical load seems to me its not happening/might want to check for an AC-idle up solenoid

Have the charging system checked to rule out a failing alternator if the alternator is not producing the correct output voltages the engine management system will not function properly-
