P0303 -> Cylinder 3 Misfire Detected

Could be a bad injector or bad fuel !



P1131 -> Heated Oxygen Sensor (HO2S) Circuit Low Variance Bank 1 Sensor 2

The test fails when the HO2S fails to switch due to circuit or fuel at or exceeding a calibrated limit.
Electrical:
-Short to VPWR in harness or HO2S
-Water in harness connector
-Open/Shorted HO2S circuit
-Corrosion or poor mating terminals and wiring
-Damaged HO2S
-Damaged PCM
Fuel System:
-Excessive fuel pressure
-Leaking/contaminated fuel injectors
-Leaking fuel pressure regulator
-Low fuel pressure or running out of fuel
-Vapor recovery system
Induction System:
-Air leaks after the MAF
-Vacuum Leaks
-PCV system
Improperly seated engine oil dipstick
EGR System:
-Leaking gasket
-Stuck EGR valve
-Leaking diaphragm or EVR
-Base Engine:
-Oil overfill
-Cam timing
-Cylinder compression
-Exhaust leaks before or near the HO2S(s)
-A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S. aid.



P1132 -> Heated Oxygen Sensor (HO2S) Circuit Low Variance Bank 2 Sensor 1

See P01131



Hope this helps !
