2007 Mazda Mazda6

Needs a little bit of love but runs and drives. This was my daily before financing a 3 row for the growing family. I drive a semi during the week and don't have a need for another car. It was having an issue stuttering over a certain rpm so I started throwing parts at it. New fuel pump, spark plugs, ignition coils, EGR valve, intake boot, MAF, O2 sensors, fluids and filters, belts and injectors. Turns out one of the catalytic converters was breaking down and clogging the exhaust flow. I had it hollowed out but now the O2 sensors don't read properly hence the check engine light. Other than that the A/C needs a recharge, the roof liner is falling down and brake pads. Some normal wear and tear like rock chips, scratches, seat tear. Front tires are less then 5k miles, rears still healthy. Recent alignment, maintenance followed. Any other questions let me know thanks
