I brought the car to the honda dealership to have it checked out but i don'tunderstand all the codes. I know need a catalytic converter & a tune -up. I've never gotten a fuel injection. What should i get done first the catalytic converter or the tune -up? Is it expensive to replace the P0401 EGR? What does P0302, P0303, P0304, P1259?

Do the tune-up first before replacing your converter. This is because if your engine isn't tuned up the un-burnt fuel can ruin your bran new catalytic converter.

Those codes (p302,p0303,etc) are all mis-fire codes. Meaning a cylinder isn't firing properly (must likely caused by a foul spark plug or wire)

Is that the reason why the car is shutting off while I'm driving? When should I get the fuel injection?
