Hi,

A couple of days ago I did the whole EGR/IACV cleaning, and I accidentally touched this screw which I circled in yellow below. I've now noticed that my RPM at idle is always at or just below 500. It sometimes sounds like its going to die when I'm coming to a stop. I've been reading that I may have touched the idle screw but I couldn't find a picture of what it looks like and want confirmation. If it is the idle screw I touched how can I fix this problem? Thanks.
