Where is the air flow meter situated on the motor

The air mass sensor is located on the left hand side of the engine compartment. Follow the large hose which starts out as plastic down and to the front of the car. you will reach a rubber hose about 4" in diameter. It is attached to the back of the air mass sensor.
They stopped using air flow meters in 1979 (I beleive) Then they switched to what they call a "hot wire air mass sensor".

The mass air flow meter is located at the air box where the air filter is housed.

Well, in a word, maybe!
I am writing too you from the U.S.A., and it appears wee do not import that model here.
Therefore, I could not look up that part.
However, I did look up the air flow meter for American imports, and I found "it looks like you might be able to."
We use "e-bay motors" for used parts.
If you will type that in, check the "Nissan air flow meters" there, and see what you think.
Be blessed.

possibly faulty air flow meter, start engine remove wire socket from air flow meter, is it better than before replace air flow meter, is this information helped you?

don't drive the car without air flow meter connected because the air flow meter signal very impotent for fuel mixture in combustion chamber, in your car faulty air flow meter replace air flow meter, is this information helped you?

change the mass air flow meter.

Try to disconnect the Air Flow Meter. It is the first plug just before the air filter/air intake box. If this improves your situation you will need to source a new or aftermarket Air Flow Meter.

mass air flow meter or idle air control motor

jjj8000: Your car uses what is called a "Hot wire air mass sensor"
This cylindrical black plastic component which has screens at both ends and an electrical connector with roughly 6 pins, is not a serviceable component. It has a set of wires inside of it which after the engine is shut off, gets to a temp over 1,000 degrees Fahrenheit to burn off residue collected on it during the time air has been passing over it. If I could repair this type of component in my shop, I would stand to make a lot of money! Unfortunately, it takes specialized testing equipment for the remanufacturing process. Not to mention the replacement components to put in to replace the ones needed to rebuild the cores.
I wish I could give you a better answer, but it's the only one I know. However, prior to condemning the air flow meter, make sure you have made the proper diagnosis. FALSE AIR problems are often diagnosed as air flow meters. Check and make sure the boots (hoses) which the attach the the air flow meter and go to the throttle body, have no tears or leaks. Make sure you have no split vacuum lines or hoses. Remember, the ECM determines the injector pulse width by the amount of air metered through that component. If any un-metered air that passes after the air flow meter, will create a situation of hesitation and stumbling, lean conditions and more. DO YOU HOMEWORK!"
I'm the new guy on the block here at "Fixya" and need all the feedback possible to get better ratings. If I have helped you, please write in. Thanks......mybunkey

The turbo uses a completely different air flow meter than the non-turbo.
