What you need to do is take a deep breath and not throw anymore parts at it.... Rent or buy a scanner that reads live data so you can see if the O2 sensors are in fact working like they should...
We are all going to need alot more info about your truck, ie, Engine, Trans ,rear gearing ,4WD or 2WD and Year ...to really help you..!!

That spark plug is completely clean, it isn't running lean (or rich) at all. They're all good burning plugs.
I have a scanner that can read PID data. The O2 sensors are brand new and are functioning correctly according to the PID data.
It's a 2001 base model. Transmission and rear end aren't even nearly related so I figured it was unnecessary information. Since you asked, though, it's an automatic with 3.73 rear end, 2WD.
