Plug

Scanner

I don't know what the BLM numbers are, but they are different from side to side with the engine warmed up. O2 sensors look about even as well.

These screenshots were taken at idle. The spark plug looks pretty decent. Thoughts on the color of the plug? It is white on the grounding strap.
