RE: Help me AEU86, you're my only hope
Just been looking at the latest video clips. In the "Air Leak Test" the screw
that you are adjusting down the tube at the side of the throttlebody is the
Idle Air Bypass screw. This adjusts the amount of air that is allowed to
bypass the closed throttle plate to set the idle speed.

When the engine died you were raising up a tube attached to one of the
vacuum ports on top of the throttlebody. If moving the tube or blocking it
with your finger stalled the engine, that tube must be supplying at least
some of the idle air. If I am correct about this then capping/blocking that
port and opening the idle air bypass screw should enable the engine to idle.

Cheers... jondee86
