3 When oil supply is incomplete.

4 The intake door is lowered, and the opening time is postponed, resulting in insufficient intake.

5 Air filter cartridge is too dirty or air filter installation is incorrect, so that the air is not smooth.

6 The supercharging efficiency of the pressurizer drops.
