My neighbor had a fuel trim exception rich code on her Hyundai, I opened up the air box and dug out a chipmunk nest and about a thousand acorns. Not to say your problem matches this, but anytime a code indicates rich mixture, I check all air intake parts for obstruction.

unplug tran's TCC plug in/on front of trans. make sure the wire/plug won't hit the exhaust.
If stops stalling at stop lights/signs then TCC solenoid is bad or fluid is old and dirty faking same problem.
But Dumping 2-4 quarts oil in the pan and filter often isn't enough. You want max oil change w/o draining the TC itself...
See my Cave, Automatic
I don't trust "transmission flush" from anyone for many reason. Many just rip you off to Can wreck the trans.
Leave it unplug until you fix whatever else.

"Presently", the car is NOT Stalling anymore, runs pretty good, it's just" lighting the SES light" and "throwing code 45". Has New air filter, new injector, no clogs. I don't think there is ANYTHING that I have NOT replaced, What could be Left ?

What's left? It could be a new bad part.
edit: Coolant Temp Sensor reading low would do it.[This message has been edited by Gall757 (edited 05-09-2018).]

I'm "almost" positive the coolant it full, but I'll check it again anyway.

That doesn't mean much. New components can be faulty right out of the box.
You need a scanner and/or WinALDL to tell you what's going on.[This message has been edited by Patrick (edited 05-10-2018).]
