Has anyone ever tried to test to see if their MAF Sensor is working correctly by the below method?
http://en.wikipedia.org/wiki/Mass_flow_sensor
"Manufacturers claim that a simple but extremely reliable test to ensure correct functionality is to tap the unit with the back of a screwdriver while the car is running, if this causes any changes in the output frequency then the unit should be discarded and an OEM replacement installed."
I think I might try this at home tonight and see since I've been getting the ever so common P1128/P1130 CEL code.
