HINT:
*: Check "Fuel Cut Elps Time" in the Data List. If the elapsed time is over 0sec, then the engine speed is high (more than the rpm at which fuel cut occurs +500 rpm). When this has happened, there is a possibility that the valve rocker arm will become loose and malfunction, so check that the valve rocker arm is properly attached (RAV4_ACA30 RM0000027IB05UX.html).
