Ethanol is Still bad, 65-70% will correct that hopefully once tank runs down starting from 65% eth will be easier than starting from 17%. Pulls were strong again, no crazy missfires back to normal. As usual. You were right. It was plugs this time. Will be ordering new Cast Valve cover, PCV system, B58 ignition with VTT coils etc soon. Want to dial this in as best we can in the mean time. Anything else I should do when I have the VC opened up?
