Here is a video I just took, my car runs and idles fine until you open the throttle body a little bit it starts to stutter until you get the rpms above a certain point (rpm unknown) then it revs fine after that but at certain rpms it just chugs and is not drive able in that range, voltage is good to the plug, resistance is good in the IACV so now I dont know where to go from here on fixing this problem
