I would have expected the tires to rotate faster, and continuously, in neutral, at 1000/1200 but your rear brakes may just be dragging, or the TC is just loose, which for a 3000 flash-stall, is probably correct.
What i ment was, that when at idle in Neutral, i just hit the throttle a bit to rev it up to 1000-1200 rpm, but not maintaining that rpm but just let it drop again back to idle.
At that time the revs jump, the tires rotate a little and when the rpm comes down the tires come to a stand still again.
Brakes are not dragging because the wheels rotate easy by hand.
And holding 1 wheel stop both obviously with a sure grip.
