Intermittent operation that changes with ambient temperature usually points towards faulty/shorted electrical wiring or failing electrical sensor [extreme cases point to fuel delivery system]. I'd bet swapping it out with a new one would fix the issue. Check voltages/resistance of the MAF and compare with what it should be from OEM. MAF's usually read very low resistance (OHMS) when good.
