Does the subject want to ask, "What is the sound of the Accord and the exhaust valve mixed together?" ? The oil circuit is blocked and the air inlet is blocked.

1. The oil circuit is blocked and blocked, and the oil pressure is abnormal: the electric fuel pump is abnormal or the fuel filter is blocked, and the pressure cannot reach the normal range.

2. Air intake is blocked, and idle speed control is abnormal: common faults are dirty stepper motor and throttle or air leakage in air intake system, abnormal sensors such as atmospheric pressure, temperature and throttle position, and incorrect data lead to control disorder. Need to be repaired in time.
