P0351 indicates an issue with the #1 cylinder coil driver. You could have a crankshaft position sensor issue, or you could have a #1 coil issue. Testing is in order to determine what the failure is. An easy way to see if it is a coil is by swapping the #1 coil to number 4 or 5 position. I say #4 or #5 because number one is the first one on the back bank passenger side. #4 and #5 are right in front of you under the hood. Don't swap with #6, because a crankshaft position sensor problem will show failure of cylinder 1 or 6 driver. It could make your swap an invalid test.
