Does it bog badly until 2500 or so and then start to pull strongly again?
Mine did this a couple of years back.
Turns out it was a faulty MAF that didn’t set a CEL.
Try unplugging your MAF and see how it runs.
The car will revert to the factory programmed fuel map and throw a CEL, but if it runs like a champ again, you’ve found the problem part and you aren’t replacing things you don’t need to.
