Question, our 2011 f150 5.0 has the p0420 code for catalytic inefficiency. I have changed up and down stream O2 sensors. I asked in the 150 forum and someone said some possible other than the cat, wiring, timing and a couple other things. only code it is throwing. Is the cat screwed?

Haven't worked on them much at all so not a lot of help but it sounds to me like its time for a cat delete or replacment.

guess I’ll try some cat cleaner through the fuel. There is a way to cheat it by using a spark plug de-Fowler. Basically just moves the O2 sensor farther away so it creates a great difference in the two readings
Happy Saturday Jim. I have no experience with that unfortunately.
Still haven't figured out the camper. Manual override didn't work. Ugh!
Got some more wiring done in the shed today. Hope to gwt a bunch more done tomorrow. I hot the two outside lights up and wired. Only one is on a switch so far. And one interior light. 7 more to go. Lol
