P0420 is a cat converter below efficiency.
All codes around P0130 are O2 related coeds.The front O2 sensor should give a fluctuating voltage at say 2000 RPM at the same time the rear would want to be relatively flat line if the cat is OK but you need to compare the readings using a two channel oscilloscope.
There's no such trouble for this vehicle. Getting the exact and all codes will assist in helping you.
