1998 Lincoln Navigator 5.4l
Codes P0171 and P0174 are present...Freeze Frame data shows it occurred at high RPM and not at idle.
I am actually using a Bluetooth OBD Scanner and the TORQUE program on Android.
Cleaned the MAF. It didn't look dirty.
The Fuel Pressure Reading on the scanner is pegged at 74.4 . Never changes.
I guess my question is...How accurate is this fuel pressure reading? Or is it even a real reading? Because it's obviously high.
I know I need to go get a fuel pressure gauge and hook it up to the fuel rail to verify. But, I'm at work and can't yet.
Thanks!
