Well as most of you know, my car is running rich. I got my CEL pulled and i am now going thru the list of things to do to the car to get it running right (from what the CEL pull told me) Im going from cheapest to most expensive.
I changed the spark plugs, cables and boost. Didnt help.
It says something about my Vacuum hoses. Now the owner before me blocked the hoses off. They took them out and capped them off. Now today when i looked at my engine, i seen the caps were bad and the vacuum hose valve was sucking in air. So i went and bought new plugs and blocked them off really good. Now my car stalls out when i start it. I have to give it gas to keep it from stalling and then it will be fine. Should i just go buy and put the vacuum hose tubes back on? What would have been the reason for taking them out and blocking it off?
Next would be the throttle body hoses/tube. It says they could be loose or torn or whatever. But i dont know where they are, so can someone point me in the direction of that?
Also, i went thru and tightend everything i could that gets preasurized. That didnt help either. I am going to do a boost leak test though. Hopefully that will help..
After i do that the last option is to get a new MAF. I pulled mine and its clean as a whistle. Maybe its defective though? Who knows. I hope i dont have to get a new one because thats sort of expensive..
Any and all help is appreciated.

When your throttle body plate is closed the engine is pulling air threw a small passage that is adjusted by the BISS. Your isc also has a hand in letting in the proper amount of air at idle
You DO NOT have to open your throttle plate at all. Thats what the biss is for.Try adjusting the small phillips screw in you throttle body. Turn it out until you have your desired idle. Also you might want to find someone with link or another tool to lock the isc in its default position. If you cant find anything to lock the isc just adjusting the biss should helpl you out.
