My truck is throwing p420 now so it's time to kill a cat. Does anyone know if just putting a spacer on the o2 sensor makes this thing happy? Better way to skin a cat?

If your cat runs away, zip tie the rear o2 to the frame.

Does this thing just not throw 420 codes if you do that?

That has been the case for many years with mine, and others I know of.
