No. it is not an issue with the powertrain swap, the entire harness was torn apart and checked for wire damage etc, and everything was fine,
This person had this issue to but it doesnt solve my problem. I have many questions to this.

It it a 0411 issue. its probably the fact the ecu came out of a 2002 suburban with a 5.3 that more than likely had case ground o2 sensors. this is a common issue it seems like but my problem is no one uploads a solution. the engine runs fine at operating temperature but it just runs rich because there's no o2 signal
There has to be somebody out there that has ran into this problem and came up with a good solution besides hacking up the harness.
