Default Idle surging in park or neu. High idle in drive

I've been having this issue for a while with my SC300 '92. When in part or neutral the idle surges very bad from 3000 rpms to almost dead. When I put the car into drive this goes away and the idle is high enough to drive the car about 45 mph on level roads. This is an intermittent problem that seems to increase as temperature increases. Any help will greatly be appreciated.
