So after reading a bunch of forums and watching a lot of videos, I decided that a straight pipe from the second cat back would be a good choice so that my car could breathe more and it hopefully wouldn’t cause back pressure problems, for about a day everything was fine and now at red lights my car has a really rough idle like it’s about to stall, and I’ve seen the other forums about these same codes and I’m wondering if it’s just a coincidence that these problems are coming up after I straight piped it
Welcome Aboard!:welcome:

More than likely just a coincidence. If you kept both cats, the only change you are going to see is that your vehicle is a bit louder.

Don't forget to introduce yourself and your Cruze here.

I have these same 3 codes today on my 2012 Cruze LTZ. Only symptom is my car idles rough when stopped like yours. Wondering how safe this is to drive 500 miles between now and the 2nd when mechanics in my town will be open.

Both of you should look at these threads:
