P0171, P0174, and P0175 Codes, Cant seem to find the problem or fix it.

Hey, This is my first time posting to the forum and my first ranger. At first, I got a P0301 code and changed the fuel injector and the code went away, but then I got the codes in the title and can't seem to fix them. When getting to the fuel injector I Changed my Intake manifold gaskets, throttle body gasket, EGR gasket, Ignition Coil, All of my O2 sensors, and Engine Air Filter. I've already checked my MAF sensor, battery, and alternator, and those aren't the problems. It has a really hard time starting, feels like I have no power when trying to accelerate, I have no power braking, blows A LOT of white smoke out of my exhaust, and the engine shakes like CRAZY!!!

You got a lot going on now, and it didn't sound like it was "that bad" before... I would reverse some of the multiple changes at once... go back to the old coil, o2 sensor so that you have only changed fuel injectors and irrelevant stuff like gaskets and air filter. depending on those results march forward one thing at a time - new coil, again test, new sensors, again test.

Both lean and rich at the same time sounds like a total cluster.... check plugs & compression test at the same time would be my first step. how long have you had it? how did it drive when you first got it? 2 months ago before the first code?

Ive had it about a year and a half and it was driving fine, just happened a random morning on my way to work, but thank you ill definitely get to putting all the old things back

IDK it applies to OP's situation or not, but I had both lean and rich codes when I wired my O2 sensor up backwards.
