This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
When ordering a 2005 to 2008 remanufactured 5.4L 3v or 6.8L 3v engine, spark plug boots may be provided in the packaging. Replace all black spark plug boots from the original engine with the 'brown' spark plug boots, as provided. The updated 'brown' spark plug boots are longer than the black boots to accommodate a running change in the spark plug length. The ignition coil bodies and spring/resistor are transferable and only the rubber boots require replacement. Failure to install the spark plug boots provided with the replacement engine could lead to drivability concerns.
