So I recently had to change my O2 sensors I mean honestly I’ve done everything under the sun to this I Sadie I’m on that for almost a year. Tonight I got Eric code P0422 and P0432 which is a bank one in BANG to catalytic converter below threshold codes. I turn to the expert wherever you are come out come out wherever you are I need help. This model has two catalytic converter‘s I just cannot believe that both are bad I went and got a whole exhaust system off of an 04S 80 however it’s a turbo and the exhaust is only one manifold out when mine Is duel then goes to a single pipe after two catalytic converter’s does anyone have any thoughts on what might else because in this. And when it gets warm also on the highway it does feel like the throttle is fluctuating.
