i own a fiesta mk 6 zetec s and have purchased a sports manifold to fit onto it, only problrm is that i noticed my original manifold has two sensors going into it one by the inlets of the manifold and one by the flexi, my new sports manifold only has oe sensor hole by the flexi. does anyone have any suggestions of how i cn get around this or can i make the higher sensor redundant or something???
