Yesterday I had a puffer light come on. I regained and the light went out but my tractor started stalling. I finally made it home and the puffer light came on again. I did a parked region and it started running fine. I parked it in the barn and left it over night. This morning it would nor start. My dealer told me to pull a plug off the cut off valve and see its it would start. Nothing. I scrolled through the screen and noticed I have engine error light P0627. My dealer is 50 miles away and I would really like to avoid taking it in if possible. It is a 2016 model I got new and I have never had any problems with it.anyone have an idea?
