    P0141 is bank 1 sensor 1 heater circuit malfunction, P0142 is rear most O2 sensor malfunction, P0462 is FUEL LEVEL SENSOR CIRCUIT LOW VOLTAGE. Poor running would more likely be O2 sensor related than fuel level sensor related.The cause of the codes need to be investigated and cured, but you may find the problem is unrelated to the above codes.
