Well, my CEL came back on. I pulled the code, just to make sure there wasn’t a new issue, and I got the PO420, the cat. Not surprised at all. I have to say though, and I hope I’m not jinxing myself, but she is running smooth, with no signs that the bad cat is causing more issues, no rotten egg smell or sluggish driving ( knock on wood).
still saving $$$$ for the repairs, little by little
