I have a 2012 Nissan Pathfinder that is stalling and shutting off while driving or in an idle position. I got a code of P0334 and had the camshaft replaced. It worked fine the day of being fixed and the day after. But today it stalled while idling and I restarted it and it cut off again. I was able to crank it and make it home but then it stalled as I was pulling in my driveway. I crunk it again and it stalled again as I pulled further in my driveway. I am not sure what the issue is again. Any ideas of what could be wrong.
