Idle Sticking

[Black Widow]

hey peeps, i've got an 89 r32 with an rb20det, for a little while now sometimes the idle will sit up around 2000rpm, and then once i take off again it drops back to 1000rpm. At first i thought this was the throttle body sticking so i cleaned it out but its still doing it? Any ideas?
