Unhappy booty shaking idle with a/c on

yesterday i used my a/c for the first time in months to defrost the windows, and when i stopped at a traffic light with it on, my idle began to fluctuate (about a 500-750rpm spike above normal idle), and then suddenly drop to where it felt like the car was going to stall (accompanied by lots of groaning and shuddering).

my a/c was disconnected for quite a while, probably 5-6 months before it was reconnected in december. my exhaust went on during the summer months (just FYI), and right after i reconnected it a few weeks ago, it seemed to work fine. my intake went on after that, along with an ECU reset. after the intake install and reset, i didn't use the a/c up until yesterday, so is this just an ECU related problem (needs to relearn idle with the a/c on), or something else?
