I've pretty much eliminated the idea thats its a vac leak. I took my propane torch, and carefully sprayed the entire intake with gas. Normally if there is any vac leak you would detect a change in idle from this.

I opened the MAS, its a 3 hotwire setup. one of the filiments is slightly discolored, maybe some imputiry burned into it? I tried cleaning it with brake cleaner, but no changes.

My next thoought if this new MAS doesn't solve the problem is fuel pressure. I'm sure i can solve this by upping the pressure, but I didn't want to have to mess with that.
