I can't say categorically, but I sure would not!
I wouldn't think it good for the throttle body, intake, fuel injectors, cylinders and electronics to have brake cleaner sprayed on / in them.
Do NOT use plain old carb cleaner or the like - ask at the parts store for the right kind of cleaner to use in order to avoid damaging this very expensive sensor. CRC makes a product specificly for your MAF sensor. DO NOT USE ANYTHING ELSE.
First item to check is the MAF sensor. Buy cleaner from NAPA like CRC MAF cleaner. Follow the directions to clean the sensor.
carefully remove the sensor, then use either electrical or brake cleaner to remove dust and grime from sensor. Make sure sensor is totally dry before reinstalling, if sensor isn't shoot this should work.
Clean the MAF sensor with CRC MAF cleaner.
Clean the MAF sensor with CRC MAF cleaner, do not touch the sensor wires, you'll damage the unit and freah is ~ $175.00
Spray it with Brake Cleaner and wipe it with a Q-Tip. Then blow it dry with air.
Get a can of mass air flow sensor cleaner and clean the maf sensor
Go to a parts store and buy a can of CRC MAF cleaner. Clean the MAF sensor.
If a non hotwire sensor buy a can of CRC MAF cleaner and follow directions.
clean the maf sensor with maf cleaner and general tune up, fuel filter and fix check engine and related problems
Dirty throttle plate- clean with carb cleaner and/or dirty maf sensor- clean with electrical contact cleaner or bad throttle position sensor-replace
The mass air flow sensor on a Mark VIII is located just after the air filter in the air filter enclosure. BE VERY CAREFUL when handling this item. If you take the air filter box out to expose the maf sensor, do not touch the sensor with anything, there are two very tiny short wires that are exposed. If you want to clean the maf sensor, there is a specific cleaner to be used on this part. DO NOT USE CARB CLEANER OR THROTTLE BODY CLEANER, you WILL cause expensive damage to the sensor.
Clean the MAF sensor with CRC MAF cleaner. Check the airfilter. Check for a clogged catalytic converter.
