Simultaneous, P0335 and P0420?
At a red light my G35 abruptly stopped. I managed to switch it back on. It sounded like it was struggling more than normal, but it turned on. After driving it home, I performed a diagnostic and found the codes p0335 and p0420. The week before, we had a lot of snow, and I remember starting my car after the snow had melted and hearing a distinct sound coming from my exhaust-almost like a deeper sound-and for a brief while, I could feel it in the seat. The day before, I was able to drive it around 60 miles without any problems, but after a week or so, it abruptly cut off. Little history, I replaced the sensors, camshaft and crank along with the valve cover, spark plugs and coil packs, it was a kit. Year later I'm experiencing this issue.
