Po420 code cat low bank 1. Have cleared code and does come back on after couple days. Today started flashing and running bad then shut off. They had a pcm recall on this. Could they not have set the pcm right. Or did this ruin the cat. And can this cause the car to run bad and miss at times. This is the 3.5 high out put.
