Thanks for the link, AB. My symptoms don't quite match what I've found on Google for the Low Pressure fuel pump, though. LPFP symptoms seem to be fuel tank noise (I don't have), difficult starts (I don't have), and loss of power (I don't have, save for the hesitation). The one consistent symptom that I have had - hesitation/sputtering when accelerating between 2k - 4k RPM - matches what Google tells me for the High Pressure fuel pump. Were you having the same symptoms as me for your LPFP:
- hesitation between 2k-4k RPM
- MIL for 2nd O2 Sensor
I'll found out Thursday or Friday from the dealership what their diagnosis is, and if anyone's interested, I'll update here with the findings and cost.
