lost cause

My brother just picked up a 2000 Mustang Gt from the auction a couple of weeks back, and it has had a weird idle problem.
When the defrost or A/C is on, the car develops a bad loping idle, and the car runs like crap. If the defrost and A/C are off, the car runs great.
We tried cleaning the IACV, and MAF after a local mechanic told us to do so, but really have no idea where to go from here. This is the first 4.6 motor we have messed with, and have no idea where to start. Any suggestions?
