My engine light came on my 1996 mercury sable. the code was for the second catalytic converter.?

Question

do i need to have it replace right now or can it wait. and how much will it cost.

Answer 1

Mine was $69 at a local auto parts store. I replaced it myself and was relatively easy to replace. You can still drive it that way, just replace it before you get it smogged.

Until then you will have a bigger carbon footprint with the increased pollution.

Answer 2

You CAN still drive it, but it won't pass inspection with a bad converter.

Sadly this is a fairly expensive part to replace.
