Fuel Rail...................
Code went ape crap this weekend then when I took Mariner to the Mechanic friend to run for more possible codes, check engine light (which came on Saturday in Butt-blank Nebraska/Iowa/Western Mo.) turned off and code canceled itself..
Now I must wait for it to reemerge so I can get the more accurate diagnosis...
2016 has been a cluster F for problems with this thing.
Love the vehicle to pieces though...
