high idle

well i seafoamed my car a few months back and ever since its had a high idle. around 900-1200 rpm in park, and drops to about 700-1000 in drive (a4). i cleaned the IAC on the bottom of the throttle body today really well hoping that would fix it, but no such luck. now i'm clueless. anyone have any ideas?

I personally dont think that idle is too high , most guys tune the idle between 900-1100.....is this cold start up or warmed up?
