    You're correct, it's triggered by the clutch switch. Once the clutch switch is released the RPMs will rise. This is dependent upon the positioning of the clutch switch, it may take some adjusting.

    Question, can the LNF head be put on the LEA block? Is the LEA crank cast or forged? And are all ecotec bellhousing patterns the same?
