I have a 2005 2.0L PZEV M/T

on cold start the engine huts for a high idle and will go as high as 3000rpm for a good 5-10 sec.
when the engine is at 200deg, my iac is at 28 duty cycle, my throttle position is at 210.78 (absolute position), and my MAF counts are at 125.87, all at idle. If I unplug the IAC motor, the motor barely runs.

I did have lean code on my up stream o2 so I replaced it. That didnt cure my issue

it is a vacuum leak. its either the hose going to the intake flapper control or the control it self. i have the feed capped off for now (flaps are removed already)
