The idle is not adjustable and is controlled by the computer. You could try cleaning the throttle body and throttle plate if the idle is not holding stable. The A/C compressor cycling will cause the idle to constantly change, That's normal to bump up whe the A/C comes on.

tried answer that was accepted, but still having problem. as long as car is in constant speed have no problem,but when having to stop at a light or drive slowly through drive through, the rpm needle jumps and the ac clicks costantly then the car jumps slightly forward. if i turn ac off car runs fine.

You have an A/C problem. It's normal for the idle to change witrh every cycle of the A/C. Youi need to find out what's making the A/C fast cycle and that will have to be done by a trained A/C technician.
