I have a 2004 Ford Explorer XLT with a P0174 code. Was wondering what could cause this problem.

P0174 is System Too Lean (Bank 2)

Also look here if you have the 4.6L V8:

I think I have a vacuum leak and I'm trying to look for the pcv hoses but I cant seem to find them on line or am I searching wrong.
@Jspillado which engine? Did you try googling for it? There might also be a video on YouTube. Otherwise, I recommend in general a shop manual or subscription to ALLDatadiy.com (if you look for Explorer it’s under ‘Ford Truck’)
