Replacing my catalytic converter
I need help figuring out how to properly buy a catalytic converter for my 2000 ZX3. My engine light is on and I am getting code P0422, and unfortunately the cat is the most likely culprit. I also have error P0455, but I don't think that is causing the cat to give that error, but I mention it just incase it may.
Anyways, I have done some research and found out it'll cost between $500 to $1400 to get that fixed (odds are the larger range). I have searched for cats online, and have seen stuff ranging from $100 to $300. I would rather do it myself to save money. Problem is I need to make sure it will make the engine light turn off and make sure the cat works well enough to get me to my internship as well as pass inspection. Hopefully someone can help me figure it out. I believe my cars engine is a 2.0L I4 SOHC 8V FI Engine. I really appreciate any advice and help in the matter!
