In the early gears it runs great, until the engine gets up to normal temperature seems like.
If you ease the accelerator down, it runs great, but if it goes more than maybe 1/4th down it chugs/misfires again. When this is happening if the accelerator gets passed the 3/4th spot, it quits misfiring but has no power and won't go passed 3k rpm.
I've been learning as I go, trying my best to diagnose the issue. I've changed the fuel filter, all 6 spark plugs/wires, and O2 sensors(None of this helped the actual issue but did improve how the car ran in general.)
Originally I thought it may of been electrical, but there is a strong gasoline smell inside the cab, so I believe fuel is too rich. Car did idle rough but changing o2 sensors fixed that.
Almost at my wits end here, running out of ideas.
Edit: Car has 136k miles, driven regularly by last owner.
Car idle:(little worse today than yesterday)
