Spark plug problems?
I have 90 vette with 85000 miles. Yesterday I Pulled two of the plugs to see the condition of them and they were both a brownish color 
. They are the bosh platnum plugs. Is this something I should worry about. If so what would the cause of this be. These plugs have about 8,000 miles on them. Thanks

light brown or tan isn't bad black is bad running rich. my plugs are white and thought i was running lean till someone on this fourm told me it's normal around town driving. if you want somewhere safe with no traffic do a run punch it out till about 100mph then pull over shut the motor pull a couple of plugs .it's WOT you should worry about.
