I have no clue why you are seeing the results when removing the Coil Plugs.. But what I do see in the O2 Sensor Voltage at Idle ( the First Shot of the Conzult Screen ) is the Left bank is running Richer than the Right Bank.. The Right T-Body and Intake control the Left Side of the Engine.. So you might have a Left Intake Side leak.. PCV Valve.. Something like that.. Or the Left T-Body might be out of adjustment.. causing the Right side to run lean.. ( It's a Balance of Air Issue because of only ONE Maf Calculation between two banks )
