I have all the vacuum lines replaced on the hot side and now I am starting on the intake side. Access is limited as the transfer case block access from the under side. How is it best to get to these? They plug into a plastic pipe that probably will break if I pull on it. If I remove the EGR valve behind the "throttle" I may be able to get my hand it. Removing the intake manifold would also work. Ideas?
