BPV Symptom?

[Phil Rose]

No, it doesn't seem like the typical symptom of a bad bypass valve.
As already mentioned by Rich, it could be a malfunction of the ISV.
If you have surging that happens while at partial throttle (rather
than completely "off" throttle) you might have a defective oxygen
sensor.
