Truck is a 2011 Ranger XL 2.3 duratec

For about two months now I've been experiencing a definite lack of power when accelerating. However, on a cold morning when I start the truck it is the worst. It will start up fine and then I'll go to give it gas after pulling out of the drive way and it will just completely bog out. After a 30 seconds or so of giving it a tad bit of gas it will allow me to get my revs up and then everythings fine (aside from the lack of power of course). Truck pulls a rich code intermittently (P0172). The code will pop up after about a week or less of driving, just randomly. I am always clearing the code after replacing parts to see if it will pop back up again. Took the pressure at the fuel rail and it was like 85 psi, so it appeared to have a pad regulator or pump. I went ahead and replaced the whole fuel pump as the regulator is apparently part of the fuel pump assembly on these ones. After doing so, my pressure at the fuel rail was vastly improved from about 85 psi to 58-60 psi. Unfortunately, the lack of power issue still persists and after spraying down with carb cleaner I couldnt find any obvious vacuum leaks. I've replaced so many parts, as I am not a mechanic.. I'd love to take it in and have someone look at it but I love learning this stuff and I am determined to figure this out and learn even more then I already have... #1 being learn how to troubleshoot and stop replacing parts lol

So far, I've changed out:

Throttle Position Sensor
Thermostat
Engine Coolant Temp Sensor
All spark plugs
All spark plug wires
All fuel Injectors
All 02 sensors
Intake manifold gasket (just to be sure)
Valve cover gasket (found a little oil on two of the plugs so I did it just to be sure)
Fuel Pump
Cleaned MAF

What should I do next? The brake booster appears to be fine and as I mentioned before, I havent found any obvious vacuum leaks. Does this sound like an EGR problem? It would make sense in my head, but I figured I'd ask the pros before digging into this, as it sits right on the firewall pretty much and is going to be a nightmare to replace.

2.3 duratec is a completely different engine than the older 2.3 lima. They share zero in common. The duratec egr valve is a computer controlled electronic step motor not a simple vacuum operated valve.

Perfect More JUNK I keep Hearing wonderful thoughts on the new 2015 4.0 motors what piles they are when the tensioners go by by Most shops tell people to trade the truck in instead of fixing that pile of sh-t to do a timing chain fix here in calif it's 3500 to 4000 they have to pull the engine cus they have to drop the dual oil pan to get all that plastic crap out of the oil pans. I will stay with my 1990--97 4.0 SOHC engines they last longer
