I'm experiencing something similar.

Look here to see what is going on:
how-diagnose-resolve-engine-issues-using-durametric

None of the replacements have corrected my hesitation issue.

Still no positive proof of what has happened and the exact fix, but my latest idea after replacing a bunch of stuff is that the computer needs a reset and 25+ miles of driving to re-adapt itself and run properly and smoothly.

Have not had the chance to do that yet.

What codes are you getting?

First look should be the MAF and airleaks in the induction or exhaust header.

A reading of the codes and LTFT , STFT (Fuel trim) values are helpful when trying to solve mysteries.
