Sorry bro don't know about mechanic but wait for other members to help. Also mention your city. What do you mean by car don't move on idle 600 rpm? Like it don't move in D gear ??
Ideal idle rpm is 700-750. With AC idle rpm should be 850-900.
Get computerized scanning and set idle rpm to 700 without AC.
They’re saying we cAnt adjust rpm its automatic
In which city you are at this moment?
