I am using Robo's site as a reference but still have a question about the connections in the picture below. There are three barbs that are no longer in use after removing EGR and AIV solenoids. Two connection to the metal tubes that run along the side of the plenum (photo shows hose still on them) and the barb sticking out from underneath the plenum.
What do I do with them?
The EGR removal was already done by a shop using 300 degrees kit.
