    Default Mass Air Flow Sensor for PCM Pro Boss 5.8

    I've had starting problems on my 1994 Supra with the Pro Boss 5.8L EFI for several years now. Latest tip was to replace the Mass Air Flow sensor. While the engine block is a Ford, the sensor is a GM. Does anyone have a part number? It appears to be a standard automotive part and I would hate to pay inflated marine prices.

    Try starting the engine and tapping on the MAS with the back of a screwdriver. Any change in the running replace the sensor. Look carefully at the sensor GM normally puts numbers on them.
