My truck is a 2011 2.3 ranger
I'm still kind of a noob when it comes to working on vehicles. I am an HVAC technician by trade though so I am naturally mechanically inclined and need help determining what my next repairs should be. Not the type of person just trying to save a dollar by working on my vehicle myself I just would really like to learn more about working on vehicles. Sure I'll screw some things up along the way but that's the price ill have to pay.
The past month or so I would get a check engine light (P0172 Rich code) that would pop on every now and then. This whole time I've been noticing that the truck would start fine in the mornings and after work, but as soon as I pulled onto the road and gave it a little gas it would lose all power and then steadily get it back as I drove for the next minute or two. Now the past few days I have been noticing that same lack of power when getting going, but furthermore, the truck is now taking probably 6-7 seconds of turning over to get it going (the prolonged turning over only seems to happen after it's been driven for a while and sits in the off position for about 10-15 minutes or so) I checked the fuel pressure at the rail and it's running about 83 psi or so, which I understand is not normal. I also found that when it is taking forever to turn over, the fuel pressure will start out barely pushing about 5 psi or so and slowly move up to about 15-20 psi and then all of the sudden it shoots straight up to 80 once fired up. One other thing I have noticed is that my engine is taking quite a while to get up to temp, especially with the heat on.
My code reader does not have live data, but when I pulled the code it displayed the STFT at -3.1 % and LTFT at -23.4%
So far what I've done:
What should I do next?
I was thinking maybe I have a bad fuel pressure regulator or pump but none of the stores had one in stock, and I also thought maybe I should change out my injectors or run some seafoam through the system to be safe also. Lastly, I thought I may pick up some new 02 sensors. Both appear to be working at the moment. I believe system 1 one was at about 7 and the second somewhere around 3.
Any help would be greatly appreciated.
Thank you guys for reading

So far what I've done:
- Change fuel filter
- Changed all spark plugs
- Found oil on the two of the plugs so I changed the valve cover gasket
- Intake manifold gasket kit for the plenum
- I have ordered a new thermostat but it will be Monday before it gets here
- Ohmed through all injectors and each one was exactly the same (11.8 if I'm remembering correctly) of course that's not to say one of them or multiple are not restricted as I did not check this.
What should I do next?
