Re: 97 ford expedition rough idle 5.4
A lot of what I m reading sounds like my 01 expedition is having. I have replaced maf, o2 sensor,pcv, and a couple of vacume hoses . Could it be the hose going from pcv the the back of intake? I know that this part is a dealer item do you get the hose from the pcv to the back of intake? there is 2 elbows one @ pcv and 1 @intake right? if this is the problem great I am not looking forward to changing the intake gasket
