Hi all. Hoping I can get some help here with a problem on my car. 
I have a problem with my car which commonly caused by a faulty mass airflow sensor (MAF). But nobody can really say for certain if that is the problem because there are a few other things which can cause the same symptoms. So basically I need some help in possibly fixing the problem without forking out a fortune on a part which may not be faulty.
I opened up the MAF (which sits inside the airfilter) and found that it contains some sort of thermistor, as well as a flap which opens as as air flow into the engine. Nothing more, nothing less. The flap runs on a resistive track so the more air that enters the engine, the wider the flap opens, and the ECU then know how much fuel to put in.
Now my first question: would there be anything different about the thermistor used in the MAF, when compared to a standard thermistor? Also, if a thermistor began to fail, could it do so intermittently or would it suffer total failure. I would like to connect a other thermistor and see if it solves the problem.
The other question: If the resistive track connected to the flap is worn, is there any way of repairing this or it something I would have to get replaced by the manufacturer?
I have a graph of what resistance vs air temperature the thermistor should register, but I cant seem to find a graph like this for a standard thermistor to compare.
(Its a 1993 VW Golf 3, if anybody needs to know)
