Hi, you can ignore the P0410 for the engine running problem. I would substitute a new MAF for the P0101 code. That should solve the engine running. The P0410 could be a bad air pump or plugged air passages in the heads. You will need to do a little testing for that code but it will not affect the engine running.
Not much you can do without a scan tool that can read live data. The MAF should read between 4.5 - 5.5 grams per second at idle and approximately 170 grams per second at wide open throttle.
