just had 5.4 rebuilt, running rough and P0174
just got my truck back, 2001 screw with 5.4 2v, from the engine rebuilders this afternoon. they told me if it continued missing to bring it back on monday.
at first was getting misfire on cylinder 8, changed coil pack on that cylinder, and now getting P0174 bank 2 lean.
it is running REALLY rough. and almost not enough power to get out of its own way!
i cleaned the MAFS, and there are no apparent vacuum leaks. the motor itself is making no knocking or tapping noises.
but i would like y'alls opinions and see if anyone else has had this experience. the last thing i want to do is get stuck paying someone to replace a bunch of unnecessary parts ($$$).or did i just waste 3500 dollars?

Sad a shop would let you have the truck back if not running correct.
Then tell you if it does not clear up!
My intuition is a gasket leak on the driver bank causing the 174 code if that is the only code.
Tell them there are Scanners to look at the live data and see what's going on.
You contracted them to do the job in full.
Good luck.

Fixed!
Just wanted to follow up for anyone else searching for the p0174 and p0308 or p030x fault codes, because I did a lot of searching and always see the issue but hardly anyone reports back to give resolutions.
My shop that rebuilt my motor called me this afternoon and let me know they had fixed the issue. It turned out to be a bad injector.
I know this isn't always the case with this code combination, and it could be several other things, but in my trucks case it was the injector. Truck runs like new now!
