The po131 bank 1 o2 sensor circuit low code came on wile driving and the truck would just rev up to about 2000 rmp and only go up to 20 mph unless I would floor it then it would get up to 4500 rmp at thirty mph and shift really hard felt like something was holding it back . I already replaced all of the o2 sensors does any one no what it could be. Also when driving the truck in over drive it would run around 1500 -2000 rpm and when in third around 3000 rpm now when its in third it runs at 2000 when the check ingine light is off
