    Ok try disconnecting the battery for 15 minutes and resetting the ECU that could be some of it.

    Tell me when you are under throttle and you back off does it really want to die then? could be your EGR valve of something else with your intake.

    try the computer reset and see what happens

    What about your fuel filter? After the EGR that is where I would check next.
