08 impreza rough idle

hey guys, i dont noe if anyone can give me some advice
I got a GH2 impreza, 1.5 and just recently i am having problems with the idle. When the AC is on..it idles erractic and sometimes stall. At this point, there is no error code or cel being displayed, but when the AC is off, evryting is fine, idles good. I change the air filter, and checked for vacuum leakage around all lines...
As I read in earlier threads, i d/c the MAF while idling, but the idle changed slightly when AC was off.........Any advice on this?

Much Appreciated.....
