HINT:
*: Check the "Fuel Cut Elps Time" in the Data List.
If the elapsed time is over 0 sec, then the engine speed is high (More than the engine speed at which fuel cut occurs + 500 rpm).
When this has happened, there is the possibility that the valve rocker arm will become loose and malfunction, so check that the No. 1 valve rocker arm sub-assembly is properly attached (See page ).
