I have heard of raw gasoline burning making white smoke, but I personally do not recall that.
That would make sense though since you also have the black smoke and the too rich fuel mixture.
Did you check the fuel pressure yet?
This is why I asked about that live data, if you want to perform this.
P0175
Diagnostic Test
1) ACTIVE DTC
NOTE: Check for contaminates that may have damaged an O2 Sensor: contaminated fuel, unapproved silicone, oil and coolant.
Start the engine.
Allow the engine to reach normal operating temperature.
With a scan tool, select View DTCs.
NOTE: It may be necessary to drive the vehicle to meet the conditions to set this DTC, try to repeat the conditions in which the fault originally set by reviewing the Freeze Frame data.
Is the DTC Active or Pending at this time?
Yes
Go to 2).
No
Refer to INTERMITTENT CONDITION.
2) CHECKING FUEL PRESSURE
WARNING: The fuel system is under a constant pressure (even with the engine off). Before testing or servicing any fuel system hose, fitting or line, the fuel system pressure must be released. Failure to follow these instructions can result in personal injury or death.
Install a fuel pressure gauge to the fuel rail.
Ignition on, engine not running.
With the scan tool, actuate the ASD Fuel System test and observe the fuel pressure gauge.
NOTE: Fuel pressure specification is 407 kPa +/- 34 kPa (59 psi +/- 5 psi).
Turn the ignition off.
Choose a conclusion that best matches your fuel pressure reading.
Within Specification
Go to 3).
Above Specification
Replace the fuel filter/pressure regulator.
Perform POWERTRAIN VERIFICATION TEST.
CAUTION: Stop All Actuations.
3) O2 SENSOR OPERATION
Start the engine.
Allow the engine to reach normal operating temperature.
NOTE: If one of the O2 Sensors Signal or Return circuit is shorted to ground or voltage, all the other O2 Sensor voltage readings will be affected.
NOTE: After the repairs have been made, verify proper O2 Sensor operation. If all the O2 Sensor voltage readings have not returned to normal, follow the diagnostic procedure for the remaining O2 Sensors.
With the scan tool, monitor the 2/1 O2 Sensor voltage reading.
Is the voltage switching between 2.5 and 3.4 volts?
Yes
Go to 4).
No
Go to 9).
4) 2/1 O2 SENSOR HEATER OPERATION
Turn the ignition off.
NOTE: Wait a minimum of 10 minutes to allow the O2 Sensor to cool down before continuing the test. Allow the O2 Sensor voltage to stabilize at 5.0 volts.
Ignition on, engine not running.
With the scan tool, perform the 2/1 O2 Heater Test for each O2 Sensor.
With the scan tool, monitor the 2/1 O2 Sensor voltage while performing the Heater test for at least 2 minutes.
Does the voltage stay above 4.5 volts for each Sensor?
Yes
Replace the 2/1 O2 Sensor.
Perform POWERTRAIN VERIFICATION TEST.
No
Go to 5).
5) MAP SENSOR OPERATION
Ignition on, engine not running.
With a scan tool, read the Barometric Pressure.
NOTE: The Barometric Pressure should be approximately equal to the actual barometric pressure. If necessary, compare the Barometric Pressure value of this vehicle to the value of a known good vehicle of a similar make and model.
Turn the ignition off.
Connect a Vacuum Gauge to a Manifold Vacuum source.
Start the engine.
Allow the engine to idle.
NOTE: If engine will not idle, maintain a constant RPM above idle.
With the scan tool, read the MAP Sensor vacuum value.
Is the scan tool reading for MAP Vacuum within 1 inch of Hg on the Vacuum Gauge reading and is the Barometric Pressure reading of the vehicle the approximately the same as actual Barometric Pressure?
Yes
Go to 6).
No
Replace the MAP Sensor.
Perform POWERTRAIN VERIFICATION TEST.
NOTE: Remove the vacuum gauge before continuing.
6) ECT SENSOR OPERATION
NOTE: For this test to be valid, the thermostat must be operating correctly.
NOTE: This test works best if performed on a cold engine (cold soak).
Ignition on, engine not running.
With the scan tool, read the Engine Coolant Temperature Sensor value. If the engine was allowed to sit overnight (cold soak), the temperature value should be a sensible value that is somewhere close to the ambient temperature.
NOTE: If engine coolant temperature is above 82° C (180° F), allow the engine to cool until 65° C (150° F) is reached.
Start the Engine.
During engine warm-up, monitor the Engine Coolant Temperature value. The temp value change should be a smooth transition from start up to normal operating temp 82° C (180° F). The value should reach at least 82° C (180° F).
Did the ECT value increase smoothly and reach at least 82° C (180° F)?
Yes
Go to 7).
No
Replace the Engine Coolant Temperature Sensor.
Perform POWERTRAIN VERIFICATION TEST.
7) EVAP PURGE SOLENOID OPERATION
Turn the ignition off.
Disconnect the hoses at the Evap Purge Solenoid.
Using a hand vacuum pump, apply 10 inches of vacuum to the Evap Purge Solenoid vacuum source port on the component side.
Did the Evap Purge Solenoid hold vacuum?
Yes
Go to 8).
No
Replace the EVAP Purge Solenoid.
Perform POWERTRAIN VERIFICATION TEST.
NOTE: Connect the vacuum hoses before continuing.
8) ENGINE MECHANICAL
Check for any of the following conditions/mechanical problems.
AIR INDUCTION SYSTEM - must be free from restrictions.
ENGINE VACUUM - must be at least 13 inches in neutral
ENGINE VALVE TIMING - must be within specifications
ENGINE COMPRESSION - must be within specifications
ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks.
ENGINE PCV SYSTEM - must flow freely
TORQUE CONVERTER STALL SPEED - must be within specifications
POWER BRAKE BOOSTER - no internal vacuum leaks
FUEL - must be free of contamination

Ignition on, engine not running.
Disconnect the 2/1 O2 Sensor harness connector.
With the scan tool, monitor the 2/1 O2 Sensor voltage.
O2 Sensor voltage should read between 4.1 and 5.0 volts on the scan tool with the connector disconnected.
Connect a jumper wire between the (K43) O2 Sensor 2/1 Signal circuit and the (K902) O2 Return Upstream circuit in the O2 Sensor harness connector.
NOTE: The voltage should drop from between 4.1 and 5.0 volts down to 2.5 volts with the jumper wire connected.
Did the O2 Sensor voltage drop from between 4.1 and 5.0 volts to 2.5 volts when the jumper wire was installed?
Yes
Replace the O2 Sensor

No
Go to 10).
NOTE: Remove the jumper wire before continuing.
10) O2 SENSOR SIGNAL CIRCUIT
With a scan tool, monitor the 1/1 O2 Sensor voltage readings with the jumper wire removed.
NOTE: The scan tool will display all O2 Sensor voltage readings approximately 5.0 volts when only one O2 Sensor's Signal circuit is shorted to voltage.
NOTE: The scan tool will display one O2 Sensor voltage close to zero and the others will read lower than normal when one O2 Sensor Signal circuit contains excessive resistance.
Is the voltage between 4.1 and 5.0 volts?
Yes
Go to 11).
No
Check the (K43) O2 Sensor 2/1 Signal circuit for damage, short to ground, open, or short to voltage. Inspect the O2 Sensor connector and the PCM harness connector. If OK, replace and program the Powertrain Control Module per Service Information.
