Re: codes P0171, P0174 Lincoln LS V6"
Same problem on my car (LS 2001) with P0171 and P0174 - replaced the plenum gasket as that was leaking but still no help with the codes and Check Engine LIght. Rod - could you please get me info on this hose/elbow you are talking about so I can forward onto my mechanic.
Thanks
