yeah Vulcan engine .?Hello, I need to do the same work on my Taurus... Yours has a Vulcan engine?
If so, you need to:
-Remove upper intake manifold
-Loosen lower EGR valve to exhaust manifold tube retaining nut and rotate EGR valve to exhaust manifold tube out of the way.
-Remove positive crankcase ventilation valve
-Remove engine control sensor wiring stand-offs from valve cover studs.
-Remove engine control sensor wiring retaining nuts from valve cover.
-Move engine control sensor wiring out of the way.
If you have another engine, I can look on the Service Manual.[/b]
