I have an 04 Sentra S 1.8L .. The car stalled to the point it almost died at a red light one day not long after I bought it. No CEL but it had 2 stored codes. P0455 and P1273. Evap and Lean shift Sensor 1 Bank 1. Long story short, the 1273 was a combination of o2 sensor vacuum leak and fuel pressure from a faulty pump. I suspect the evap also has a major leak because the P0455 came back shortly after I reset the codes AND performed idle relearn. I plan on having a smoke test done for the evap but it will be a few days.
