Will the mass air flow sensor make a car stall at idle and surge?

It can, but the MAF mass air flow sensor is a pricey part and you want to be sure before buying it. Alot of parts stores, i.e. autozone, advance, might scan for codes for free if it's a 1996 or newer vehicle. If it's pre 96, then a different scanner is needed. A car that stalls and surges, sounds like a vacuum leak. Sensors that might also do the same, MAF, IAC, EGR, etc, many causes.

Would a battery temperature sensor cause your vehicle to stall?
No, it would not. There are many things that could cause a stall at idle. The throttle plate could be dirty as well as the mass air flow sensor. You did not mention the kind of car or engine size. Is the check engine light on, is it when the engine is warmed up or cold?
Why is your 1987 Chevy Celebrity stall when is come to a stop?
This sounds like an idle problem. Does the service engine light come on before the engine stalls? If it does it should post a code. Knowing what that code is could lead to a more accurate assessment of the problem. Does the engine idle ok before you put the car in gear? Does the engine restart and idle ok after the stall? There are multiple possible causes for the stall. The IAC, idle air controller, could simply be dirty and not delivering enough air for the engine to run. If the MAF, mass air flow sensor, if faulty or dirty that might cause the engine to stall. If the Oxygen sensor is faulty that could cause a stall and generally poor running as well. It may be possible that if the TPS, throttle position sensor, is faulty that could cause the engine to stall at idle speed. If you have found out what the problem is I would be interested to know for future reference.

Check for leaks in vacuum hoses, check for a cracked or gunked up Idle Air Control valve, and check you throttle positioning sensor.
