Rough idle, stall, misfire problems.

10 g/s is way too much at idle. It should be around 3-4. Turn off all electric devices (AC, radio, lights) and check it again. You could try unplugging the MAF and it will default to a throttle position map. This will light up your dash like a Christmas tree but if it runs, it will let you know if your MAF is at fault.
