Idle Speed - 1985 500 SEC

Does anybody know the correct idle speed for a 1985 500 SEC. The idle speed on mine is between 450 - 500 in park, 350 - 400 in drive. I think it is a little low, and the motor shakes a little because of it. If anyone would let me know the idle speed AND how to adjust it, i would appreciate it!!

New idle control valve, idle control box, ovp, fuel pump relay, fuel pumps, injectors.
