Ford tech needed
#21
what code were you throwing? I have been thinking injectors. Cause it happened after my cousin took my intake off. The first time they tried to take the rail off cause they couldn't get the quick disconnect off....When they got it off they put the injectors that they had gotten out back in...

Need a scan tool with live data viewing to be sure, everything you have stated makes me believe they may have kinked or pinched the new intake gasket (O-ring) and/or cracked the manifold by over tightening it, I would want to look at how the O2 sensor is switching in real time, it may be going bad. .

Maybe he over torqued the manifold bolts and cracked it, maybe he didn't have the gasket positioned correctly and pinched or ripped it, maybe he don't know crap about drivability.
Yes I am Ford factory trained and certified, some say certifiable. But I know what I'm talking about when it comes to issues like you have.
You came here asking for possibilities, now you have some but refuse to accept them?
Lean codes can be elusive

I have mentioned several possibilities but still would need to watch the O2 sensors switching with a scan tool.

When I said I would need to watch the sensors switching in real time I meant exactly that, your pictures are static and useless, a video would help, also forget about sensors 2, those are catalyst monitors and mean nothing at this point, that fuel rail pressure reading makes no sense, it can't be pressure (PSI) and Vacuum (Hg) at the same time, it's one or the other and in any event the reading also makes no sense, there is no way your engine can produce that much vacuum if that's what it is and if it's actual fuel pressure then you have a bad regulator.
I don't think I would trust what ever scanner you are using. It's difficult enough to diagnose hands on much less over the net, find a qualified drivability tech and let them have at it. Painfully obvious the ones working on it now have no clue.

Need to look at O2 sensors bank 1 sensor 1 and bank 2 sensor 1 check them after engine is warmed up at idle and 2000 rpm's engine load% and maf voltage. Stft both banks. Video that as well as the sign wave you posted previously. Cancel all other parameters.
