Without feeling the vibrations, it is difficult to tell what is actually going on. Hopefully this is resolved before the need to make another video, but if you do, hold the throttle when it stumbles a little longer. If I understand correctly, it was rev'ing freer during the first few seconds, but not consistently.
Looking forward to the TPS readings. And Note: Earlier I wrote you should see around .8 volts while probing between the A and B connectors. This is WRONG, probing the A and B connectors will give you the reference voltage (4.8ish volts). Then probing between the B and C connectors will give you the variable output voltage, which should start around .8ish volts.
