i am having more car issues, and had to pull the motor out of the car. the tops of my pistons look like this. and its not just one.... they all look exactly the same with the same amount of coverage and the exact same clean spot. the carbon buildup is much thicker in persion than it looks in a pic. plus the pic was taken with my blackberry tour, so its not fantastic.
too rich or lean? not enough octane even though i am running 93?
