You could be getting the lean codes because the DME is shutting down the injectors to prevent you from destroying the trans with aggressive driving, however as you continue to drive the car, the DME is still monitoring the engine and with the injector(s) off you now have a "Lean" condition.

Don't drive aggressively and see if you still get the injector shutoff. From your previous video it looks like if you didn't drive aggressively the truck accelerated normal.

Edit:

When you replaced the fuel rail, did you replace all the o-rings on the injectors? Disturbing the old o-rings could also be a source of a vacuum leak. Any time I pull a fuel rail I would replace all the o-rings and put a little oil on the o-rings so they go back into the intake manifold easily.

No O-rings were replaced, unfortunately. I am going to run the engine without any load (no driving, just start and giving it gas) and see what codes it throws at me if any, and what issues it gives me. More videos in the afternoon after work.

The codes from last time the cog yellow light came on was:

P0732, P0102, P0500

Right now, the only codes are P0171, P0174.

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Shift Solenoids
- Shift Solenoids harness is open or shorted
- Shift Solenoids circuit poot electrical connection
- Transmission mechanical problems
- Transmission hydraulic control circuit.

P0500 may mean that one or more of the following has happened:
The Vehicle Speed Sensor (VSS) is not reading (functioning) properly.
There is a broken/frayed wire leading to the vehicle speed sensor

Causes: A code P0500 may mean that one or more of the following has happened:
The Vehicle Speed Sensor (VSS) is not reading (functioning) properly
There is a broken/frayed wire leading to the vehicle speed sensor
The vehicle's PCM is not correctly configured for the actual tire size on the vehicle

Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly. If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure will depend on your make and model of vehicle. If everything looks OK, replace the sensor.

ahhh... speed sensor... that could be an issue... there is another thread going on right now about the speed sensor as well... you need to test if the speed sensor is reporting to the ABS module... there are pinouts of the ABS plug out there, i even posted it once... need to search the posts to find it...

diddy, do you have a multimeter that can measure a diode? that is what a bmw speed sensor is, a Hall effect sensor based on magnetic field and a diode...

As I understand, you are having the same symptoms as before. If that is the case, IMO you should eliminate that it is the same problem for the same reason then check if it is the same problem for a different reason(s) as that is the greatest probability.

I understand you would be ignoring the new codes but the same symtoms for an entirely different cause has very low probability. If that is reality there must be an explanation why the symptoms went away after the fuel pump change was done when that was not the problem or at least closely associated.
