I experienced the same.
It was the mass air flow sensor

Were you able to just clean it or did you replace the maf? We're you pulling codes Po420 and P0430 or were misfire codes. Thanks

Dealer replaced the sensor.
Sorry, don't know code.

New oem cats and o2's and and no more problems. $$$ Thanks everyone.

Yeah, it's big bucks but you did it the right way.

 

[Ben Mullins]

My guess is the mass air flow sensor

you likely could have replaced just the o2 senors. sucks my first post was ignored. you spent money you did not need to.

glad its fixed though....

Something caused to O2s to fail, just saying.

o2 sensors have a service life sir.
not saying something didnt make them fail, im just saying its not as simple as saying that a ghost made them fail. o2 have a service life 100%, so to not know that means you dont see the full picture.

replacing the o2 to get a proper reading and adjust your repair course of action off good o2s with good readings is what SHOULD have been done. not throwing parts at it until the codes go away.

thats dum dum talk.

Well, I won't make an assumption without knowing what the Ford techs found.
