Ive have an code P0175 System Too Rich Bank 2. So I've replace fuel injectors, spark plugs, two O2 sensors, air filter, map sensor, and pcv valve. I have no idea of what it could be.Saw something that it could be coolant temp sensor and fuel pressure regulator. Or could it be the catalytic converter? Maybe someone here may know. Also one of the fuel injectors has two hole where the others have four. Im wondering if that could be an issue?

Update, The injectors I bought off of RockAuto where the wrong type. Even thought it said it fits the truck. The mechanic that I used was able to find the right injectors.

I take it that fixed your too rich problem?

Yep that was part of the fix, besides of replacing the o2 sensor and re-wiring some in the injector and clips.
