pulled plugs

[funguy]

i pulled my plugs because my car started to misfire again while @ WOT.

all my plugs are all a deep orange colour, new plugs for 2 weeks. I cannot seem to find an answer to what that means. anybody with more experience know?

i do have an MSD DIS-2 and i still don't know where the misfires coming from. i have no regapped them to a .026 hopefully that helps.

Are you running octane booster or any other type of fuel additive? If so, the red/orange color is caused by this. Run a full tank of pure gasoline and see if the misfire/plug color changes.

i think you got it, i was running the NOS racing additive octane booster for my last time at the track.

I'm thinking deep orange might be from the AFR being too lean. Any other visible damage or anything to them?

Lean condition causes the plug to be white or glazed, not orange. Octane boosters, fuel additives, and sulfur contamination causes the red/orange color.
