SOURCE: code PO131
Code PO131 is O2 sensor circuit low voltage , bank 1, sensor 1. That sensor I would say is the one in the exhaust manifold. I would check voltage to the sensor from the computer. If the voltage is not 5 volts, then it could be a computer problem or a wiring problem. I have seen factory wiring and connectors give a voltage problem. Check for a damaged or burnt, pinched wire. You need to know for sure that the voltage is correct to the sensor. Intermittent problems are hard to trace , but patience and knowledge helps.

You can buy adaptor plugs that allow a simple hook up at most car stereo places. However, when you increase the power going to the speakers you also have to replace the speakers to handle the higher power or you'll toast them.

1st try and search for a vaccum leak, due to the fact that these vehicles have had some bad problems with the length of wires and hoses, if there is a vaccum leak in the vehicle somewhere that will trigger other malfunctions in your vehicle. Using a can of starting fluid or Brake cleaner spray lightly spray around our engine til you hear the motor rev-up and the spot you have sprayed will determine where your vaccum leak will be. And then check under your distributor cap for any moisture be sure to take a rag and wipe and residue off. Also check the firing order on your distributor.

this shows that the oxygen sensor on the left exhaust pipe before converter is bad,
And the front oxygen sensor on the right exhaust infront of converter is bad.

Those three codes point to shift solenoid and/or clutch problems according to the Dodge Service Manual
Find someone with a Chrysler scanner and monitor the trans speed sensors, preferably the input one, make sure there is a rpm readings on both when you drive the vehicle, if ok, do a 2nd gear clutch test, if failed, internal clutch failure, if ok, replace the trans solenoid pack, it has an internal failure
