You pulled the plug on the ICP sensor and it made no difference, the ICP sensor is not the culprit.
Unplugging the ICP sets a CEL, and will use default pressure values and other PCM inputs to keep the engine running. My truck has an erratic idle, if I unplug the ICP, it purrs like a kitten.
There are very few things that will cause an engine to run intermittently on one bank, and most of them are electrical, ie; harnesses, or IDM etc.....
Have you checked the IDM harness, and the harnesses UNDER the valve covers?
