Hello everyone. This is my first Ford and Im trying to diagnose the codes. Has 135k miles on it. Coils and plugs have been replaced in the last year. Blasted intake valves also last year along with a couple of oil leaks fixed. It seems to always have a stutter or miss not sure if that is typical on the ecoboost. I have forscan but not completely competent on how to use it. Ill post some of the data and hopefully yall can help me out. I believe cats are toast but dont want to replace and have another issue that will burn them up. Thanks

 

Did you ever resolve this issue? I'm having similar issues with a '15 ecoboost. Same stutter. Replaced the plugs, I haven't done the coils yet, thought I may have a bad coil...it seems upstream of O2 and cats.

 

I’ve had similar issues with my 2019 2.7L. Drove me nuts for the past several years. What I have learned through trial and error is that topping off the gas tank can contaminate the cats. No idea why but when I stopped topping off the tank my check engine light stayed off. After several months I mistakenly topped off the tank and the code came back.
This might not be your issue but it’s simple to check.
Good luck.
