The mass air flow meter should only be changed after a suitably skilled diagnostician has checked the output on an oscilloscope and declared it to be faulty. Fault codes relating to this component can be generated by EGR valve problems or air intake leaks. If your Airflow meter is really faulty I would expect your Malfunction Indicator Light to be on. If you can get to Hants I could check it out for you. Hope this helps.

A mass airflow sensor or air sensor is a device used in fuel injected engines to measure the mass, amount or weight of air passing through it. They are placed on the intakes which deliver air into the engine's combustion chambers. You can refer this link to learn about mass air flow sensor.

I changed the idle speed control motor and gave it a tuneup but i am only getting 11 mpg. what can I do to help out my MPG problem?

These cars are natural gas guzzlers. I recommend making sure the coolant/ water mixture is according to spec's as well as the thermostat. These two items control the engine temperature and this is what the ECU uses to increase fuel trim if engine is cold
or decrease fuel trim if engine is warm.
Also keep Mass Air Flow Sensor clean (it has an air temperature sensor in it)
Timely oil and air filter changes will also help .
Make sure tires are in good condition and properly inflated.

Low miles per gallon

Hi the first thing you might want to look at is low tyre pressures or a fuel leak? After eliminating those i would look at the MAF or mass air flow meter. If you unplug your air flow meter with a hot engine and drive it there should be a large difference in performance, if there isnt then replace the MAF as it is faulty.
