I’ve been chasing my tail on a 2010 equinox 2.4 p0420 set checked freeze frame data it always sets at idle and the post cat o2 reacts the exact same as the upstream,and only in cold weather it has cold start misfire that immediately goes away once it starts warming up and never sets a code for misfire,runs great otherwise no misfire under load or at idle once it’s warm

What are the odds that the downstream 02 is failing vs the cat given the mileage?

It was the catalytic converter. I believe it was caused by excessive idling

What if theyre using low quality fuel or is that kind of been debunked as a factor in failing cats?
