I was just curious the one in my car reads 1.45g/s at 700 RPMs. Also, when the engine is off key on or when the MAF sensor connector is disconnected, the MAF reads 0.37g/s. Does the manufacturers provide specifications for air flow at idle, or at several engine speeds.

MAF sensor reading at idle should typically be around 2 to 5 grams per second (g/s). This range can vary slightly depending on the exact conditions, such as engine temperature and altitude. The reading with the sensor disconnected is probably normal.
