Hey hope someone can help me with my problem. just got a 04 g35 coupe and am fixing it up. the check engine light was on and i scanned it, scanner said it was a fuel sensor code P1273 sensor 1, bank 1. so i got it replaced and the light went away. the light came back on a few days later and the scanner said it was the same problem, same sensor. what can this be? can it be an electrical problem? the car runs fine and ive been driving it with the engine light on no problem, but i hate having to see that light on knowing that something could happen. so hopefully someone can help me with this. thx
