Default Help! Can't figure out lean codes.

Ok 99 4.0 OHV. So far this truck has had the fuel pump, MAF, TPS, Intake gaskets, two O2 sensors, Injector O rings, replaced.
Two independent shops and the dealer have gone through the truck. The PCM has been reprogrammed with updates. It has been checked for vacuum leaks many times. I even checked myself. I reset the ECU and within two days the CEL is back on.
Im stumped. The truck runs great and otherwise has no problems running ,starting , idling or driving.
Any ideas? It's been smogged and won't be due again for two years so it's not a pressing issue but Im anal about things and it bugs the crap out of me not knowing what's wrong. BTW this truck came stock with no EGR system. The codes are lean bank 1&2.

Do you have access to a scanner that will do live data?

I have a few good tests to give you but I need you to have a scanner that does live data.

Not saying this is your problem, but I have seen lean codes caused by failing injectors without any other driveability symptoms.

No scanner but the Ford dealer had one on it. They had it all day and were stumped too.

Im hoping you guys might have more ideas on it. I have been spending all my free time trying to figure it out.
Things I have thought of but haven't checked yet like a bad gas cap, Bad connection somewhere, EVAP purge valve leaking, Stuck PCV, Leaking dip stick, You know the stupid stuff. I have to write them down as I think of them so I can check them the next day.

I have a 2000 Ranger 4x4. I drove myself crazy trying to find the cause of my lean code. I changed the fuel filter and cured it. I know it sounds strange, but it fixed mine.
