Re: Platin/ums, and acceptable color thereof

["Arun Rao" <rao@frisbee>]

	Talking about plugs, I took the ones on my '85 5KT out yesterday
	looking for a solution to my month-old rough idle/low-rpm
	stumbling problem. They're Bosch Platinums, and about 25,000 miles
	old. Plugs 1 through 4 all have a white coating on them, but
	plug 5 is grayish. No trace of oil, and they look fine other
	than this coating.

	Can I infer anything from the color of the electrodes? Is there
	a "normal" color?

	-Arun

	PS: The rough idle/stumbling remains, despite yet another ISV
	cleaning.
