I'm sorry but I have to respectfully disagree with the dieseling only being caused by carbon
I never said that was the only reason, but that it was not caused by a timing issue since no spark is igniting the fuel at the point where power is turned off at the coil and plugs. Other things can
contribute to the amount of dieseling, but how else does the fuel continue to ignite in the combustion chamber with no spark from the plugs?
