I WAS getting the PO420 code practically all winter. It'd come, then go away, then come back, then go away... From what I've read on previous threads, running with this code won't hurt the engine since the code is from the cat, so I just let it go.
Funny thing is...it started once the snow started falling (I swear it happened the first time we had an accumulation). And since the last snowfall, I haven't seen the code at all, especially since it's been warming up.
It's made me wonder for a while now if environmental conditions may assist in kicking the code in.
