Answer 1

P0031 Bank 1 Sensor 1 02 sensor heater circuit low

P0037 Bank 1 Sensor 2 02 sensor heater circuit low

P0443 Evap purge solenoid circuit

P0132 Bank 1 Sensor 1 02 sensor shorted to voltage

P0137 Bank 1 Sensor 2 02 sensor shorted to ground

The symptom that is describe resembles a fuel problem rather than these 02 sensor code that are set. Yes these code are problem, but to back fire and sputter until you floor it, this is fuel problem

​ This fuel pump came from a Dodge, situation that happen here is the vehicle would run good for moment then bog down to a point of stalling, let it idle by by putting you foot all the way down the floor was the only way to keep it from stalling out, Then out of nowhere it recovered and ran just fine. and accelerated fine, what happen is the fuel pump strainer on these tends to fall apart allowing debris to enter the fuel pump causing it to jam internally, and starve the engine for fuel, The fix here replace the fuel pump module
