P1130: A/F Sensor Circuit Range/Performance (Bank 1 Sensor 1)

that means the bank 1 sensor 1 air fuel ratio sensor is missreading and it could be due to a dirty MAF sensor, or could be due to a bad bank 1 sensor 1 Air fuel sensor.

i have a feeling its a dirty MAF sensor or a failed one because if it was the o2 sensor it would usually throw a o2 sensor code, vs the a/f code that you got, so clean the MAF and hope for hte best, may be a vaccum leak after the MAF sensor and to the cylinders causing the missread also!
