Stock BT 20v on stock electronics.

1ZZ/1NZ COP Wiring:
IGT - Spliced between ECU and ignitor
IGF - Not Connected
12v Power and Ground

Coil and ignitor is in place.

** Problem is possibly due to bad ground on the cylinder head. Does not appear in another swap.

Whistling / cricket noise is the rear PCV outlet, a small piece of tape over to change the airflow fixed the problem.
