IAC maybe?

I have a '92 350/4l60 Xcab and it seems to have a higher idle after its warmed up and driving, it seems to come off high idle a bit as it sits and warms up but when i go and drive it and stop at a light or something its idling higher but as im sitting there it slowly starts to drop and idle where its suppose to, im just wondering if its the IAC or something else. Any ideas?
