Lazy Super Duty
Yet another Ford diesel annoyance: Some 2008-2010 Ford F-Super Duty vehicles equipped with a 6.4L diesel engine may exhibit a lack of power, with an intermittent DTC P0088 at full operating temperature, during moderate to heavy acceleration. A calibration update is available to address the concern.
If this DTC is found in memory, reprogram the PCM to the latest calibration using IDS 79.05 and higher. Calibration files are available at www.motorcraft.com.
