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
