This all started a month ago. 2012 F150 V6 EcoBoost w/168K miles. Had a misfire and had my mechanic scope it and changed 1 coil. Run fine for a week or so then experienced same situation again. All coils were the original ones except for the replaced one. I bought all new OEM coils and have replaced them. Truck runs perfect and gets18-24 mpg here in the mountains. We live in an RV park and the last 2 days when I went over the speed bump entrance the rear end seemed to bang, set a code P0151 Sensor Circuit Low Voltage Bank 2. Does anyone know what it refers to? Thanks

 

Disregard this I found the thread on this subject.

 

What was it?
It is like reading a book and the last pages are cut out.
