What does MAF mean


MAF stands for Mass Air Flow. Your MAF meter is located in the inlet snorkle between the air filter housing and the throttle body.

Change thermostat on 2004 chevy impala?


first you need drain engine coolant down below thermostat. what engine type 3.8 or 3.4 need to know.the 3.8 engine thermostat housing on top intake follow top radiator hose to thermostat housing.the 3.4 engine you have to remove air filter housing with air inlet duct with mass air flow sensor.you have to remove throttle body with coolant hoses.go to auto parts store buy new throttle body hoses old ones will be hard to remove might have to cut two small hoses also buy new throttle body gasket also. before you can remove throttle body unit you have to remove accelerator cable and downshift cable from bracket bolted to throttle body.once throttle body remove then you can remove thermostat housing bolt remove replace thermostat.

    Where is the Mass Air Flow Sensor located in the vehicle?


    MAF sensor is in the intake air duct between the air filter and the throttle body mounted on the intake manifold. MAF sensors are mounted directly to the throttle body.

    1996 explorer 4.0 181000 miles ... cranks and idles fine try to accerlerate it dies... cranks right back up .. making a humming noise through the breather... replaced mass airflow sensor and the check...


    check for a leak in the air duct between the air filter box and the throttle body. When the mass airflow sensor was replaced you may have failed to get tight connections and any leak in this ductwork will cause problems with driveability. Also check for any thin or soft ruber spots in hoses between PCV valve and the intake. Any holes in these will cause the vehicle to run poorly but normally would be noticed at idle also.

    Engine dies out above 2500 RPM, picks back up at 2000 RPM


    That's a characteristic of Nissan engines when the mass airflow sensor is not working. My 1990 300ZX was set up the same way - when the mass air sensor fails, the car won't rev above 2500RPM in order to safeguard the engine. Get some air intake/throttle body cleaner and clean the mass air sensor. Get some electrical contact cleaner and clean the electrical contacts on the harness plug that plugs into the sensor. If that doesn't cure the problem, you'll need a new sensor.

    The mass air sensor is in the 3-4" diameter pipe between the airbox and the throttle body.

    Where is mass air flow senser on a 1989 buick regal


    Hi

    Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
    On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

    Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

    Please do accept the solution if the issue is resolved or else revert for further assistance.

    Thanks
    Rylee
