Hi all, I recently picked up a 1999 3.0L 4x4 ranger step side and have been having some problems. The truck ran fine for about 1300 miles, and then I started to have a rough idle and it started to lose power and struggle at highway speeds. Truck runs rough at idle, then well above 2500 rpm, but low on power and revs out upon accelerating trying to make up for it. I have gone down a rabbit hole of replacing things, IAC, plugs and wires, coil pack, injectors, some vacuum lines, vapor purge canister, MAF sensor, and intake manifold gaskets while doing injectors. No matter what I've done the problem still persists. For some reason I am mechanically sound, but have a hard time diagnosing things. The latest codes its throwing are P0175, P0302, and P0301. All relating to fuel/air mixture. To me it feels like the engine is being choked, or not getting enough air. I have not been able to find similar problems online so I thought I'd post here and hope someone has some ideas on what to do next.
