I agree with Dito your MAP readings are on the low side, should be closer to 95kpa or so, unless you have a vacuum leak. I would be checking around for some mechanical reason it is reading low, it may lead to figuring out the erratic airflows, as well. I think there is more than one PID for logging airflow, think it might be Aircharge or sonic flow, etc. The one you are logging might be the one that toggles between sensed and calculated map readings and will fluctuate wildly as it does so.
