350ztilldeath

I cant seem to find anything on how to fix my 2004 350z touring. It has 46k miles, only mods are Berk HFC's, invidia gemini dual catback, and aem long tube intake.
The problem was happening before any of the mods were put on.
It idles normal when cold. Then when it's warmed up it will stumble between 500 and 750rpms. Turning the a/c helps a lot but it's still there. I cleaned the maf sensor and did all the resets. I'm clueless?????
