Default 92 SC 400 rough idle, need help

Alright guys,i know you are all going to rip me a new one but my car had a really rough idle whenever I'm at any sort of stop, i know you guys are telling me search, and i have but i came up with two things iac and vacuum lines, any help would be appreciated.

Also sometimes to counter the rough idle i turn on the a/c and it keeps it around the 600 RPMs

Again thanks in advanced and all is appreciated

Codes? Any other strange behavior? Can you hear a vacuum leak, or sucking sound in the engine bay?
