Not start with weak and short cracking

Okay, the 300 is a misfire code.

Did you check the fuel pressure? That is a common cause for this code.

What kind of EGR valve do you have? Is it a linear valve or vacuum?

131 flow chart is below for you to follow.

Let me know the results of the testing.

CIRCUIT DESCRIPTION
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content of the exhaust stream. When the vehicle is first started, the power-train control module (PCM) operates in an Open Loop mode, ignoring the HO2S signal voltage when calculating the air-to-fuel ratio. The PCM supplies the HO2S with a reference, or bias, voltage of about 450 mV. The HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage once in Closed Loop. A high HO2S voltage output indicates a rich fuel mixture. A low HO2S voltage output indicates a lean mixture. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature, and to provide an accurate voltage signal. If the PCM detects that the HO2S 1 voltage remains below a calibrated amount for an excessive amount of time, DTC P0131 will set.

Each HO2S 1 has the following circuits:
A HO2S 1 high signal circuit
A HO2S 1 low reference circuit
A HO2S 1 heater ignition voltage circuit
A HO2S 1 heater low control circuit
A low reference loop circuit

CONDITIONS FOR RUNNING THE DTC
DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0121, P0122, P0123, P0125, P0128, P0410, P0440, P0442, P0443, P0446, P0449, P1441 are not set.
The Air Fuel Ratio parameter is between 12:1-16.5:1.
The TP sensor parameter is between 3-35 percent.
The system voltage is between 9-18 volts.

CONDITIONS FOR SETTING THE DTC
The PCM detects that the HO2S 1 voltage is less than 140 mV for more than 30 seconds.

OR

The PCM detects that the HO2S 1 voltage is less than 600 mV during power enrichment (PE) mode for more than 10 seconds.

ACTION TAKEN WHEN THE DTC SETS
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

The fuel spec is 52-59 with the engine running.

The fact it drops to 48 pounds tells me the fuel pump is the issue with misfire code.

The 131 code may be related to the low fuel pressure. It could not adjust the fuel mapping so it coded for it.

What is the pressure with the engine running?

Roy

What is the pressure at idle with the engine running? You did not state that pressure, just with the engine off.

Roy

Okay, first, why are you erasing codes? That does nothing at all.

Check the hose from the mass air flow to the throttle body and make sure it does not have any rips or tears.

I attached the flow chart for you as well. Let me know what you find.

I also attached the connector diagram for you as well. Verify voltages to the connector.

https://www.2carpros.com/articles/how-to-check-wiring

The connector is a common failure.

The other codes will most likely return as clearing will not work until diagnostics and repairs are made.

CIRCUIT DESCRIPTION
The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The power-train control module (PCM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. A small quantity of air entering the engine indicates a deceleration or idle condition. A large quantity of air entering the engine indicates an acceleration or high load condition. The MAF sensor has the following circuits:
An ignition 1 voltage circuit
A ground circuit
A signal circuit

The PCM applies a voltage to the sensor on the signal circuit. The sensor uses the voltage to produce a frequency based on the inlet air flow through the sensor bore. The frequency varies within a range of near 2,000 Hertz at idle to near 10,000 Hertz at maximum engine load. If the PCM detects the frequency signal is less than the possible range of a correctly operating MAF sensor DTC P0102 sets.

CONDITIONS FOR RUNNING THE DTC
The engine is running.
The ignition 1 signal is more than 8 volts.
The idle air control (IAC) position is more than 2 counts.
The above conditions are met for more than 0.5 second.

CONDITIONS FOR SETTING THE DTC
The PCM detects that the MAF sensor frequency signal is less than 1,200 Hz.

ACTION TAKEN WHEN THE DTC SETS
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

DIAGNOSTIC AIDS
Inspect the harness of the MAF sensor to verify that it is not routed too close to the following components:
The secondary ignition wires or coils
Any solenoids
Any relays
Any motors
Inspect for any contamination or debris on the sensing elements of the MAF sensor.
A wide-open throttle acceleration from a stop should cause the MAF sensor parameter on the scan tool to increase rapidly. This increase should be from 7-12 g/s at idle to 150 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
A high resistance of 15 ohms or more on the ground circuit of the MAF sensor may cause this DTC to set. A high resistance may cause a driveability concern before this DTC sets.
A high resistance of 15 ohms or more on the ignition 1 voltage circuit may cause this DTC to set. A high resistance may cause a driveability concern before this DTC sets.
If the condition is intermittent, refer to Intermittent Conditions. See: Computers and Control Systems > Initial Inspection and Diagnostic Overview > Intermittent Conditions

Those are just your monitors that are not set from you clearing codes all the time.

What repairs were made for the 102 code?

Roy

You stated that it appeared after replacing the mas air flow sensor.

Please explain.
