Figured it out, noticed the maf scaler was hot as a mofo while poking around. Turns out that it was outputting 0lbs of airflow at all times... no cel at all. Only time it set a cel was if I unhooked it. My guess is the pcm was smart enough to ignore the 0lbs under load but not smart enough while idling. My brain hurts. Anyways hooked the maf up directly and flashed the tune back to a non scaled maf table and the car runs like a dream again. All of that work for nothing. Oh well.
