Default Car will not stay running issue.

Hey guys, it's been a bit since I have talked to you, but I have an issue on a car that is starting to boggle me a little bit, here is the info I have so far.

Someone bought an 88 TII (great shape) that will not idle, I decided to drop in and take a look and see what was up, this is what I have gathered so far.

Car will start when cold, go through AWS, then drop back to death with a slight pause around 1k like it is trying to idle.

Car will start when hot, but shut right off afterwards.

Car can be kept running with a light modulation of the throttle.

Car will drive and boost, pulling VERY strong to redline.

No unusual smells, spills or audible leaks.

I have checked the usual suspects with the tools I had at my disposal. I plan on testing the TPS for giggles and perhaps swapping the BAC for one I know is functioning. So my question is, besides for a vacuum leak (which is next on my list of things to do) what the hell else could it be that I am forgetting here? I thought MAF, but the fact that it drives perfectly in vacuum and boost makes me not think that. (I also hear no boost leaks)

Other info.

Looks like the EGR was removed and blocked, going to double check that to make sure it was blocked appropriately, but it looks like a pro job.

Everything else is dead stock.

Ideas?
