Hello. My name is ***** ***** I will be assisting you today. I see that you are having issue with this vehicle. The codes that you have provided are indicating misfiring cylinder(s) and catalytic converter inefficiency. How many miles are on the vehicle? When was the last time you had the vehicle tuned-up? This is usually caused by faulty plugs, coils, or fuel injectors.

Here, I am attaching code and vehicle specific information for codes that you have provided to give a better understanding. What you need to do is have the vehicles plugs, coils inspected, as they are the most probable causes. Although, misfires can also be caused by vacuum leaks and you should have this inspectred.

You will likely just end up replacing the plugs and coils.
