any feedback is much appreciated. I just dont know where to go next... would be nice to get the computer read or something to see whats going on.
for those who dont download the video...
i try to start, and it wont unless i sort of pump the gas why starting. After it starts, if I keep on the pedal it'll stay started. After a little bit It'll idle on its own. But then if I press the gas it'll bog-down and cut out and try to die. And as mentioned before, once it warms up it idles fine?

Compression testers only cost $20-30. You've thrown this much money at it already, what's another couple of bucks?
Is it cold out? At temperatures below zero, the warmup afr can be as low as 4:1 because most of the fuel doesnt atomize and is just passed through the system and out the exhaust. When the engine is warmed up, most or all of the fuel atomizes and the computer adjusts the afr towards stoich. It could be that upon starting/running the car after sitting for a while and its running pig rich to warm up quicker, the IAC isnt opening to allow extra airflow so it doesnt flood out. Just a thought.
Oh yeah, and my roommate wanted me to tell you the reason you're having problems is because your flux capacitor is bad...yeah
What i would want to do is get the car on a scanner and see what values you have on the sensors for cold as opposed to warm. That may point in a specific direction. I would also want to see where the car starts to idle fine. Does it clear up once the ecu goes into closed loop or just a specific temp. Is the condition it clears consistant?
When cold the ECU works with a set enrichment. The ECU doesnt monitor mixture to conpensate. When warm the ECU reads o2 and adjusts the mixture to meet the targe AFR. That could be why you dont feel the problems at high rpms liek you normally would with clogged injectors. Then again it might be leanign out top end and you just dont realize it. Poss bad gas as well.
