    Proper fuel pressure specs? 08 5.4L

    Can anyone tell me proper fuel pressure specs for 2008 5.4L V8 Expedition? As a bonus, how low should fuel pressure drop with snap throttle test before you’d think there’s an issue? Suspecting a fuel pump issue with my expedition but trying to confirm with fuel pressure check

    PO171 & PO174 both banks lean 08 5.4 L

    Thank you for this….I did completely remove the throttle body and cleaned it. I think the part you’re referring to is the idle control value, however I can’t find that on this car and I’m wondering if these models do this electronically or something because I can’t find it to clean or replace

    08 Occasionally Stalls on Acceleration after idle

    Would this explain the 500 rpm at idle? Would you say that’s abnormal?

    08 Occasionally Stalls on Acceleration after idle

    Bought this 08 Expy with 162k on it. Owners were honest in letting me know it had once sputtered after accel at a stop light. Owned for a month and it did it to me. It lost power for about 10 seconds and fired back up. No engine code. Mechanic had no solution due to no code they “felt” it was...
