What is your question?
Engine buck/misfire at all speeds, no fault codes. Poor fuel performance. Replaced most sensors on engine, no improvement.

I'm sorry you replaced "most sensors" - probably is not sensor related. A diagnostic test is required to find out what is causing the bucking and misfiring. It can be a vacuum leak, an air intake leak, a spark issue, a fuel issue, and even an exhaust restriction issue. Until you test it all, you won't find the solution.
