I was wonderin if I can get some help with a check engine light. I am throwing code P1274. I have downloaded the service manual but was unable to find the specific listing. I went to autozone and this is what they have listed

Definition: AF sensor rich shift detectedProbably causes:1.-Failed AF Sensor2.-Fuel injector or pressure regulator fault

The code has been on since I bought it not too long ago. My car has a CAI and didn't know if that could be a cause.
