Chrysler Sebring Code P0171, can't find problem.?

Question

I have a 2000 Chrysler Sebring Coupe with the check engine light on.

It runs fine, but I gotta get that light off to pass the smog test.

I have a scan tool, and I have done everything I can think of:  took off upper intake manifold, checked fuel injectors, replaced intake gasket, egr valve gasket, both oxygen sensors, pcv valve, cleaned maf sensor and put new gasket, all air hoses connected, checked for leaks with engine running spraying carburetor cleaner, no leaks.  I'm going under the vehicle next, it seems to be leaking oil, so maybe lower intake manifold or something down there, any more suggestions???

A code P0171 may mean that one or more of the following has happened:
•The MAF (Mass Air Flow) Sensor is dirty or faulty
 Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
•There could be a vacuum leak downstream of the MAF sensor
•Possible cracked vacuum or PCV line/connection
•Faulty or stuck open PCV valve
•Failed or faulty oxygen sensor (bank 1, sensor 1)
•Sticking/plugged or failed fuel injector
•Low fuel pressure (possible plugged/dirty fuel filter!)
•Exhaust leak between engine and first oxygen sensor

Has the car been running hotter than normal? above 170 degrees?  One of the tech sites I go to says something about Chryslers and this code have something to do with running hot.  And then a lean air/fuel ratio. but they offered no solution yet.

You could have had a master mechanic find and fix the problem by now a hell of a lot cheaper than throwing all those parts at it guessing!!
