EBPV opening and closing on the fly?

It's starting to get cold here and I am noticing something odd in the mornings on my way to work. I'll be going along under light load and suddenly I'll feel a loss of power and a "whooshing" sound. It feels exactly like an exhaust brake would feel. Is there any reason for the EBPV to be opening and closing like that?

If it seems excessive, the sensor the PCM uses to control it may be getting a bad reading because the tube feeding it is clogged. Lots of threads on clearing the tube and the fitting in the manifold (and the sensor itself).

I plan on deleting it over the winter anyway so I'll just wait until then to play with it. I just thought that after it opened up it stayed open until you shut it off and got cold again. I didnt know it had the ability to open and close multiple times, especially while you're moving.

For now you could just unplug the electrical connector that is under the intake side of the turbo.
