Moving the injector is the most work so Im going to move the coil first and replace the plug, just looking for a source of compressed air first to clean out the plug cavity.
Referring to image 3:
Range 0.785 to 0.840 is the yellow line, Bank1 Lambda(colour not visible on the axis)
Range 0.1 to 0.9 is the blue line, Bank 2 Lambda
Range 680 to 725 is the red line, Engine RPM
The colours stay the same for all the graphs but the ranges on the axes differ. Bank2(blue) is the problematic one. Both of the banks are running rich because the fuel system is running open loop due to insufficient temperature.
