have you checked the tps or mafs wiring? the mafs can do some crazy stuff. I had an oscillating idle with the first couple times dying off from a mafs issue so don't rule that one out either.

if you need to recirculate the bov just to test the mafs, then just unplug the bov (block off the vacume line) to the bov and manifold, that will keep the bov from opening, also, Im wondering if you or whoever did the wiring used shielded wire for the mafs???
