So today on my way to work i logged driving using DSMlink just to see what was happening at 3000 rpm when the CEL comes on (for knock.) In the log the boostest was not even 1psi and knock shot up to 12.7 degrees, and timing dropped to 5*.
Does this sound like knock that would be caused by a noise?
Im pulling the transmission over the long break to see if maybe there is a loose flywheel bolt or something rattling around in the clutch. But to me it would seem that the knock should not shoot up like that over a rattle.
