Idle adjust on 87' 420 SEL


Can anyone tell me how to adjust the idle on a 420 SEL? It idles at about 500rpm while in drive and 600 in park. In drive the idle is a little rough and if I press the pedal a little to raise the rpm to about 650RPM its smooth as silk. So I would like to raise the idle a touch but can't seem to find the adjustment. Any help will be appriciated.
