Intermittent Stumble, runs rough

After ~30 miles of highway driving this morning, my '05 9-5 Arc started to stumble/run poorly. Initially it stumbled/ran poorly when in gear at a stop light, but ran smoothly in neutral and at speed. Later it ran fine at idle in Drive but ran poorly/surged/etc. at highway speeds. No check engine light, and no codes thrown when I checked it later w/ OBD-II reader.
I swapped the ignition module for a new one and all was well, but it was also well when I reinstalled the old module, so I don't think the ignition module is the culprit.
I'm thinking that the air mass meter could be bad. I got a "Pending P0100" code once while test driving with the OBD-II connected.
Crank Position Sensor was replaced a month ago.
Any thoughts/experience that might help?
