A bad AMM will throw a code. Unplugging it will throw a code, but if it starts and idles nicely while unplugged and the sysmptoms come back after plugging it in then the AMM needs to be cleaned or replaced. Driving the car without the AMM plugged in is not possible.

I would check for a loose vacuum hose, or a leak in the hose from the air cleaner to the throttle body.
Have you checked the PCV lately?
