    I recently started having a bit of a stutter in the low rpms of my '98 Expedition. I then got a CEL and scanned to find:

    P0171
    (system too lean Bank1)

    and

    P0174
    (system too lean bank 2)

    codes. I proceded to spray the MAF with electrical cleaner, but to no avail. It actually ran worse. I then went and got a new Maf, but still no dice. What should I be replacing or checking?:confused:

    If its too lean that means its not getting enough fuel. Run a fuel system cleaner first- its the chepest fix. Then try the filter, then the pump, then the injectors.
