I got a few codes on my 99 civic lx and I need help on fixing it and reading a code.

My codes are:
67- which came up as cat converter? How do i fix this do I just replace the o2 sensor on the cat?

code 70: at/ transmission? it will be helpful to know what the code means or how to fix it.

I also have code
71; random missfire in cylinder 1
72; random missfire in cylinder 2
73; random missfire in cylinder 3
74; random missfire in cylinder 4
How do i fix code 71-74?

Thanks for any help.

Severe engine misfiring may have killed the cat.

Regarding the misfires, check the plugs, wires, cap, rotor, coil, and ICM.

Thanks for the help Ron. I replaced the spark plugs and resetted my cel. Code 67, 71, 72, 73, 74 are all gone. The only cel I have left now is cel 70. Which is a/t transmission. Any idea on how to fix it? Thanks again Ron
