Fellow S-Heads,

Anyone have a good link to color photo's that would help explain how  
to read the deposits on spark plugs?

I used to have a nice print from an old Toyota service manual, but I  
can't find it. It was pretty useful in that it explained all the  
colors variations in color pictures.

Audi content is that I've developed a stumble, burrrrp, under WOT  
(again- - - -sigh).
