My 99 f250 5.4 2v vin L 4r100 when I put it in gear it’ll idle fine until I give it some gas and it starts bogging down and when I let off the gas it dies out I’m getting codes
P1131 lack of HO2S11 switches-sensor indicates lean
P0135 o2 sensor heater circuit bank 1, sensor 1
P0155 o2 sensor heater circuit bank 2, sensor 1
lean codes are old but it’s still running lean, trans and torque converter related codes are new I drove this thing a half hour to my brothers house last night and a half hour back home this morning and it was acting fine went to take it out and this was the condition it did this shortly after I started driving. Shut it off and unplugged the battery for an hour or so and it didn’t help at all I checked the pigtails on the trans itself and they’re all plugged in and nothing seems torn and split and the overdrive light doesn’t flash or atleast hasn’t yet
Update: was messing with it earlier and realized that I can unplug everything on the passenger side of the motor with no effect (coil packs and injectors) coils are producing spark and the injectors are spraying. However when I do the same to the driver side it’ll die almost immediately. Any opinions?
