A po131 indicates bank 1 sensor 1 O2 sensor is shorted to ground. Check the wiring to the sensor first and make sure nothing is shorted, melted. If it is good, chances are the sensor is bad.

We took it to a place they put a computer on the jeep, it showed a code po340, p0320, p1391. We replaced one of the senors. But the car when it gets to 2000rpm, it won't shift, runs rough, wants to stall. I'm sorry we are getting information as it is given to us. All the help you can give us would be appreciated. Thanks

We took the car to a auto zone they hook a computer to it. It came back with codes of p0340, p1391, p0320, It still won't go pass 2000rpm, want shift, runs rough, wants to die. Any information would be appreciated. Thanks

I would recommend starting with the cranks sensor. Have it checked.
