You can easily eliminate the MAF by simply unplugging it. The car will have to adjust for a short period, and the CEL will come on, but the car will no longer stall with the MAF unplugged if it is the cause. If it continues to stall with the MAF unplugged, and if the tach suddenly drops to zero just prior to the stalling, the crank position sensor or the wiring between it and the ICM are probably the cause.
