My car seems to go threw spark plaus every 4,000 miles. I thought I was burning really rich because my gas mileage sucks, and it smells like it. Something isnt right though.
Last 2 times I have changed my spark plags, the seem to come out whiteish. I changed my plugs last time because my car seems to misfire when they start going bad. The last time I changed my plugs the misfiring went away. Yesterday it went away. It is back today...
I didnt think I was burning lean the first time I changed my plugs. I just thought it was the Amsoil P.I. I put in there. Well my plugs tell a different story.
Here is the one I just pulled out. I only pulled 1 out because I didnt have time to pull the rest. Going to the Wolves game. Let me know what you guys think.
(Seems like best lighting is in my bathroom...)
Here is an old one with about 3 - 4000 miles on it (right) vs. a new one with maybe 100 - 150 miles on it... (left)
