P0391 Camshaft Pos Sens B Circ Range/Perf Bank2
Think I would just replace the cam sensor first. Its fairly inexpensive, and easy to change. It just hides under the distributor cap. (yeah, a fun spot to work in.....) Disconnect the battery, change the sensor, reconnect the battery, drive the truck. See if the problem is gone.
