Could dat be the reason why my idle is going wild?
probably letting more air through then needed
so the iacv may adjust the amount of air that goes into the A/F ratio
but by having a hole there there is more air then the ecu has taken into and tries to compensateso you go a fluctuating idle
just a possible cause

While we are on the subject
What else have you done to the car that you have not told us about?
