Based on some help and suggestions, I might be experiencing High Speed Glazing:
APPEARANCE: Glazing appears as shiny coating on the plug, either yellow or tan In color.
CAUSE: During hard, fast acceleration, plug temperatures rise suddenly. Deposits from normal combustion have no chance to fluff off; instead, they melt on the insulator forming an electrically conductive coating which causes misfiring.
RECOMMENDATION: Glazed plugs are not easily cleaned. They should be replaced fresh set of plugs of the correct the condition recurs, using plugs with a heat range one step colder may cure It.
Based on a post on Ultimate Spark Plug Reading Thread: http://forums.bimmerforums.com/forum/showthread.php?t=1282968
I need to move to a colder plug. So I'm now on the search for the proper colder plug.
Thanks,
Will
