Hey, take care of you and yours. I just don't want you to be waiting on me, I'm just thankful for the help.

I was able to get the fuel sensor in today. It reads 2.94v @idle on ad1, assuming I did the math right that's 61psi at the rail.

Min PSI: 0
Max PSI: 100
Min V: 0.5
Max V: 4.5
------------------
Slope: 25
Intercept: -12.5
PID: "{EXT.AD1} * 25 - 12.5"

Take care and thanks for everything!

At idle, HO2Sx1 are very low (almost zero) and do not switch...

this indicates either of the following:
- air leak somewhere in-between MAF and front NBO2's;
- MAF could be under-reporting;

( at part throttle, your MAF seems to be a bit low )

this is causing g/cyl to be low, which causes trims to go high and meet the criteria for setting the bank lean DTC's.
