The way you describe the problem it sounds to me like when it switches from open loop to closed loop fueling the problem starts, which would indicate a problem with the feedback from the wideband. Watch your data stream and look for that switch from open to closed loop.

He stated in the first post he does not have a working cable for the ACCEL 7, thus monitoring the data stream would more then likely be impossible as well.

Well then have to do it the hard way and monitor AF sensor voltage input with scope or dvom. Or possibly unplug the AF sensor keeping it in open loop.
