Fault code, p1339 combustion misfiring (impact on catalytic converter)

If it is a petrol engine it could be an ignition coil fault on cylinder 3 or possibly a spark plug. Note 3 is from the gear box end. However, if you post your vin admin will be able to look up this fault code against your car.

You have a 1.6 THP 16V 163 (EP6CDT M).

As for the second P0313 fault, not a good idea to run with low fuel levels when trying to troubleshoot fuel problems, as this just adds to the issues.
