ok so we pulled my head off and the plugs were indicating the motor was running rich
from my research these cars always ran rich
but everyone knows.. lean goes...
so what's the possible ways I can lean the mixture out a hair
I know different plugs would be one way
making sure o2 sensors are doing there jobs maf is good
forcing more air in (currently doing this on the way )
I already run high octain maby germans have higer octain ?
