Was it a new maf fitted or a referbed unit
most new mafs sold only have a 6 month warranty
are there any other fault codes present or just the maf fault code
I agree with you a fault in the maf can make the car behave that way
the maf has a few functions with sensors in the unit
other sensors can also cause the engine to behave that way
02 sensor / faulty transmission solenoids and TPS
different car maker
i have just done a diode jump at the ECU
bypassing a faulty sensor in a maf
so far maf throws a fault code but no more problems

SERVICE IT .....OIL PLUGS, AIR ,FUEL AND OIL FILTERS GET TROTTLE SENCOR AND THE MASS AIR FLOW SENCOR CHECKED

actually it works in battery. check the coil associated with the RPM meter or if your battery charge is low recharge it. You ll get it fixed :) Please rate this!!

tell your mechanic to look up Service Bulletin #96-032 this could fix your problems

I just had the same problem with my '02 altima SE.
Took it to Buckeye Nissan in Hilliard OH. and they had to replace the two crank sensors which.
The sensors themselves were about $44.00 a piece, but w/labor about $300.00 was the total. Hope this helps.....Now if I can just get the heater working!

P0100 OBD-II Trouble Code
Technical Description
Mass Air Flow (MAF) Circuit Malfunction
Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.
You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes
A code P0100 may mean one or more of the following:
* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.
Possible Solutions
Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:
* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.
