auto-gsr-civic

Ok I have a jdm 18c motor with an udm ls autmatic tranny in my 00 civic hatch. As of lately there has been a bad sputter, I have taken a video of the sputter in action. It only happens after the engine has gotten to running temperature. car has ~110k and the motor is 30k-60k as per normal jdm swaps go. tranny mileage is unknown. Plugs wires and distributor cap were changed within the last 3k miles, ngk laser platinum plug bdw 7mm wires and a bdw distributor cap. The speedometer will drop to 0 at about 22 seconds into the video. Car has ngk wideband, afc neo afc, ihe, the wideband and the neo were also added recently. Sputter occurs with or without air map control on the neo. Any help would be appreciated.
