I picked up a Professional Products Upper Plenum and it is missing the hole for the vacuum line in the picture below so now my car throws a code P01443. I think the line is for my evap purge valve, but I don't know what that does either. Should I be concerned and see if I can get a new plenum?
Do you need this vacuum line or can I just cap it off?
