A mechanic will inspect your fuel injectors, spark plugs,
airflow sensor, tires and other important components to reach an accurate diagnosis.
It is possible that the mass
airflow sensor itself could be causing this issue.
The signal from the mass
airflow sensor should steadily sweep from 1.9 to 5 volts as you press and...
Rough idle and excessive shaking of the engine could be due to a bad tank of gasoline, dirty fuel injectors, incorrect idle speed, exhaust restrictions, vacuum leaks, incorrectly installed or damaged spark plugs, a defective or clogged fuel pump or fuel filter, failing electrical components such as the ignition control module, plug wires, coils, and spark plugs, a defective
airflow sensor, dirty oxygen sensors and other causes.
Dirty
Airflow Sensor: An
airflow sensor detects the mass of air that is entering the fuel injection system and passes that information to the engine's computer so it can correctly deliver the right amount of fuel.
A failing or dirty
airflow sensor will send the wrong signals to the computer.
Stalling at idle could be due to a faulty mass
airflow sensor, faulty camshaft or crankshaft position sensors, worn spark plugs, wires or defective ignition coil (s), inadequate fuel delivery or pressure (clogged fuel filter, injectors, faulty fuel pump or pump circuit), contaminated or old gasoline, defective throttle position sensor, faulty idle air control valve, leaks in the EGR system, intake vacuum leaks, and so forth.
The mass
airflow sensor (MAF) helps the engine's computer maintain optimal combustion.
You may have a misfire, broken motor mounts or a mass
airflow sensor or intake tube leaks.
If, though, no codes have been stored, you can consider the typical causes for immediate stalling which are a faulty mass
airflow sensor, faulty engine coolant temperature switch / sensor (typically at...
I would recommend having the mass
airflow sensor tested by a qualified professional to determine if it is functioning properly.
If no codes have been stored, you can consider the typical causes for immediate stalling which are a faulty mass
airflow sensor, faulty engine coolant temperature switch / sensor (typically at cold start only), faulty camshaft or...
Mass
Airflow Sensor: The mass
airflow sensor measures how much air is entering the engine and relays this information to the vehicle's computer so that the right amount of fuel can be delivered from the fuel injectors.
The O2 Sensors or the Mass

An issue with the mass
airflow sensor may manifest itself when a car starts and then stalls soon after starting.
It sounds like there is a problem with the mass
airflow sensor, in that it may be dirty or faulty.
Performing a volumetric efficiency test can reveal the accuracy of a vehicle's Mass
Airflow Sensor (MAF) as well as potential issues with the engine and can be the key to successfully diagnosing and fixing a vehicle.
but this should be cross checked with the mass
airflow sensor.
Keep in mind, the mass
airflow sensor could also be defective.
I had the same problems and a forum somewhere told me that there was a Mazda 626 directive telling a Mass

I would check and test any intake air temperature sensor, water / engine temperature sensor, and mass
airflow sensor.
My brother - in - law (not professional) suggested cleaning the mass
airflow sensor (haven't done this yet, since reading some horror stories of people trying to do this themselves).
Other things you can do is to ensure you do not have any leaks in your intake tract after the Mass
Airflow Sensor.
Simple answer that all the forums seem to agree on, and that my garage also approves is that you will get better airflow to the manifold, however unless you also adjust your ECU, and potentially replace your Mass
Airflow Sensor (depending on exactly what you are changing in the airflow path) then you may have problems.
The Kansas State University - developed system uses
an airflow sensor to measure and control the airflow rate into each piston in real time.
Aside from greater autonomy and resiliency, Ferrari said her lab plans to help outfit RoboBee with new micro devices such as a camera, expanded antennae for tactile feedback, contact sensors on the robot's feet and
