The IACV (idle air control valve) is an electrical solenoid that allows more air into the engine to raise idle under engine load conditions. The IACV is fastened to the intake manifold plenum by 2 flange-head hex screws.
I understand your problem with the idle screw slot for flat-blade screwdriver. You need to remove the silicone, if there is any. Then, you need to use the tip corner of a flat-blade screwdriver to make the slot deeper. Do this until you have a deep enough slot. Then, use a flat-blade screw driver that is about as side as the slot, apply pressure towards the screw while turning. Once you break it free, should be easier from there.
