All right gang my 01 325i was running while buying a soda with wife in the car; purchase said soda (mexican coke) and while car is in reverse pushing down on gas pedal the car stalls and nearly dies. I put it in park turn off turn on rough idle. Restart again somewhat improved. In drive press gas and delayed reaction still sputtering but enough to get home.

Check codes in the morning:
P0313
misfire detected w/low fuel
P1347
misfire cylinder 3 with fuel cut off
P0171
Bank 1 too lean
P0174
Bank 2 too lean
P0102
mass air flow circuit low (something like that)

Start car the next day everything fine. WTF? Clean MAF anyway and swap out ignition coil 3 with ignition coil 2 and clear codes. as well as clean spark plugs (little residue).

Run for a while fine with only a few instances of delayed acceleration when stalling not nearly as severe.


3 codes came back
P0171
P0174
P0102

no obvious vacuum leaks

Whats the solution to the stalling/dying?
I'm pretty sure the 171 & 174 codes are O2 sensors needing replacement.

Thank you for the help.

UPDATE: Removed intake boots to check for leaks (None Found) as well as cleaned DISA valve.
same three codes

I would inspect ever vacuum line and air intake elbows they tend to rip and sometimes you can't even see where from.
