Unplug the MAF as well...and try to start it...if it starts fine and idles fine with the MAF unplugged then you need a new one...if nothing changes...then that rules that out.

Possibly damaged?

No idea...it needs to idle anyways and re-learn the fuel trims.

Something else...do you have a rear o2 or a o2 sim in there? That could be another issues as well.
