01 Blazer rough idle

Any Ideas? I have a 01 Blazer ZR2, 140K runs good but idles up pretty high at start and rough at red lights/stop signs, usually after driving a while (engine pretty warm). changed IAC seemed to help for a few days and then back to the same rough idle. No SES lights. any suggestions?
