I have a CEL on a 2001 5.4 F250. Comes back as lean condition on bank 2. I cleaned the Maf sensor and air filter was good. I just replaced the PVC valve. Think the other side of the line is good. Its a pita to even get my hand back there but feels dry.
I tried to check for leaks by spraying brake cleaner but didnt notice anything. Most people with bad Maf sensors have code p0171 also. So I was leaning towards a air leak or low fuel pressure.
Any advice or where to look? Spose to bring it in for emissions and this code keeps coming up.
