You may need to replace the Mass Air Flow Meter Sensor:
·Causing poor engine acceleration.
·Causes the intake pipe to "backfire".
·Automatic transmission unable to shift into overdrive.
·Data fast exceeding standard.
·Black smoke emitted from the exhaust pipe.

Attention should be paid to installing the air flow meter:
·The air flow meter should be installed at the inlet of the fan or fan to avoid measuring at the outlet of the fan or fan.
·The installation of the air flow meter should be maintained in a vertical direction, strictly following the installation height and angle specified in the installation manual.
·In order to ensure stable flow measurement, the installation of the air flow meter should avoid areas where the air flow is unstable, such as vents, duct bends, etc.
