Check engine light came on vehicle shut down,Nissan Wingroad Y11,on checking with tech it showed Air flow censer, changed it drove about 50metres light came back on car stutter shut down. help

First inspect the boot from sensor to the intake manifold for cracks,inspect all the vacuum hoses to the intake.
second unplug the connector and inspect the terminal.Sometimes the plastic is burn and the wire pusht out of terminal. insert the wire all the way in or replace the pigtail.
plug scanner and monitor the air flow and air temperature on live data.
inspect the wire harness for damage to engine ground.

I'm having trouble starting altima 02. I have to open the air filter case and block the air hole to **** in air to start the car

Sounds like the Mass Air flow metre has broken down! this regulates the amount of air flowing into the engine when mixed with the fuel.
These are normally situated on the air intake hose after the filter housing and before the carburation unit or throttle housing! or failing that check that all of the hoses to and from the air box are good! also check the vacum hoses as well!

hope this helps

Idle and Power Where is the fuel filter?

Fuel filter is inside the gas tank and its built into the fuel pump housing. You need to remove the back seat and get into the tank via access hole under the seat. Than you need to "split" the fuel pump assembly open and get the filter out. Reverse procedure to assemble. Those filters are rated for 105k miles. My 00 Maxima has 167K on it and it runs just fine with the original. As far as the air flow meter , its a pretty common part that fails and that's why 00 Max air flow meter costs only $100 and all others $500 or more. If you replace an air flow meter, make sure that you use a "NISSAN" air filter or YOU WILL BE replacing the air flow meter AGAIN. Also with the new air flow meter the cars ECM/Computer needs to be reprogrammed. As far as plenum gaskets leaking?? unless someone had it apart and didnt put it back together the right way, its "VERY UNLIKELY" for those gaskets to be bad. Totally bullet proof.

Have you checked the power and ground supply to the MAF. They are right the barometric pressure sensor and the intake air temp sensor are built in to the MAF.

Fuel conumption too high toyota camry dx 1990 model

just an idea... install a free-flow air filter like a K&N brand filter for example & then get the air flow meter adjusted again... if you can afford it, a shop with a dynamometer & performance tuning skills will be able to do the best job for you. there may be a user-adjustable ECU available for your model so you can set it up for economy by you as needed too...
