Changed Oil Now Rough Idle & Hesitation

Good Afternoon everyone! I have an early 04 6.0 Excursion in which I just changed the Oil and Filter on yesterday. I now have a small lope in the idle only when it reaches operating temp (normal when cold). I also have some hesitation/miss/buck/sputter between 1300rpm to 1900rpm when in a higher gear or overdrive.

Any thoughts?

I also replaced both fuel filters at the time of the oil change.
I put in 14 qts of Valvoline Blue and the reading on the dipstick is halfway.
The EGR was cleaned less than 1000 miles ago and no signs of water.
The coolant level is consistant.
No DTCs or dash lights.
It will start fine, hot or cold, sitting for an hour or a week. NO need for the block heater.
It will puff a small amount of black smoke under heavy heavy acceleration (which I think is normal).
The truck is bone stock (was a Mommy Mobile) with 92,400 miles on it.
The previous owner had it only serviced by Ford.

Thank You

@cj performance

I double checked the oil filter and both fuel filters. Put the included brand new seals on as well.

I changed the oil first and then the next day I did the fuel filters. The rough idle occured after the oil change and I didnt notice a difference the next day after I did the fuel filters.

I wonder if it is the proline oil filter I used that I bought from Pepboys? It is the correct filter and it appeared in brand new condition.

Thanks for your help

I could be corrected, But, in all honesty the only filter you should use in your 6.0 is the Motorcraft filter. As well as the factory top. There have been many posts on this subject.

I used to use wix filters, but they were junk, liked to collapse and cause No start issues.

Yeah I was in a pinch and needed an oil change quick. I'll pick up a Motorcraft filter and replace it. As for the hesitation between the rpms mentioned above, I'm wondering if I havethe turbo veins sticking or possibly a lazy egr that is not fully closing. The funny thing is that the hesitation or occurs at operating temp, not when cold. Correct me if I'm wrong, bug doesn't the egr valve stay closed until the engine is at normal operating temp?
