Yessir. Might be the cat itself though. You can swap the downstream sensors and see if the code follows. If it doesn’t then it’s the cat.


I would love to be able to swap out the sensors from side to side. Crappy thing is that was the one that was replaced last year.

I just tried that, they are in there. Trucks got 113,*** miles it stutters occasionally at slow speeds. I’ve been told it’s the AFM.

It’s due for the yearly inspection, gonna ask to see if the cats are needing replacement.
