It was a miss fire code for cylinder 4. We had to switch it to the other bank to make sure that was the problem.

 

brand new gaskets...and the mechanic that had it last could find no leaks at all

 

I can see some of the things on my phone though with a cord I have....I'll look tomorrow

 

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

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 hate the lean codes I've had them for two weeks and at 2 repair shops and still can't fix it bout to throw in the towel

 

in not refusing. I'm telling you that leaks and cracks have been checked for o.O. I'm taking my kids to school today in it and I'm going to look at the O2 readings and report back to you...

 

All pics were taken at 2800-3000rpm

 

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.

I will try to get you a video, I could do it alone. 80 inHg = 39 lbs of fuel pressure. I'm just trying to get some help until j have $ to take it to ford man.

 

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.
