Just unplug it and warm it up, then see if it bogs and acts stupid. If not...it was the Bosch sensor. If so, we look into other things.
My initial thought was TPS, but since it seems to work fine in open loop mode, I think we can eliminate that as a cause.
It wouldnt hurt to remove the coil and see if it's cracked on the back side, either. But usually a bad coil will eventually cause the PCM to kill the engine, not limit the revs....which brings us to Zeejays question...(assuming he thinks it's a timing related issue.)
