Ford E250 2005 4.6L Engine Stalls with Codes P2272, P2112, P2107, and P0446

Model: Ford E250 Fault Code: P0446 Posted: 2020-05-11 09:59

I'm experiencing a serious issue with my 2005 Ford E25-0 4.6L engine. The vehicle drives normally at first, but suddenly the engine stalls while driving. After parking, shifting to neutral, turning off the ignition, and restarting, the engine runs again—but does not accelerate smoothly. I've already replaced the coil pack (bank F), the oxygen sensor for bank 2, and the backup ECM. Despite these repairs, the following diagnostic codes persist: P2272, P2112, P2107, and P0446. The intermittent stalling and poor acceleration are concerning, and I'm seeking advice on how to diagnose and resolve this issue effectively.
