My 2000 Saturn SL1 won't pass inspection due to the catalytic converter reading "not ready." I already looked up prices for catalytic converters but I don't know if there could be something wrong with it and not necessarily have to replace it. How can I find this out? And if I do have to replace it, how difficult would it be to do it myself vs. Taking it to a professional mechanic?
