J32A2 (B-series TB) low idle after cold start

Greetings, comrades. First question - is anyone else out there running a B-series throttle body with some sort of adapter for the idle regulator, like the one made by P2R?

I am, and I wonder whether my troubles have something to do with that or not. I've tried three different idle control motors, and nothing changes - my engine won't go higher than about 900 revs in idle after a cold start. Is anyone else out there with a B-series TB swap experiencing the same problems, or is this just my bad luck?

It might have something to do with the TPS sensor voltage adjustment on the throttle body?.

That's unlikely, it has been properly calibrated. You do have to cut the slots a bit with the B-series TB to get the voltage right, but it has been done. I think it might be that the TPS itself is malfunctioning, but the only way to find out would be to replace it.
