Answer
Hi Jason,
Surging and/or dying but with no codes: the first thing that I suggest is always that the EGR valve be checked to be sure the valve stem moves freely via the internal spring-action and that is closes to a dead stop. Spray some WD-40 on the stem where it enters the valve body proper and move it back and forth with the tip of a screwdriver inserted into the slot of the stem. Then see if that has solved this issue or not.
Otherwise you will want to use a diagnostic readout tool to observe the reading of all the sensors to see if one of them is out of range from normal but not so badly as to set a fault code.
Thanks for the detailed history.
Please read the PS (below) and respond to it.
Thanks for doing that.
