$3500... Overpaid?

There are few problems. When I bought it, it was running and idling good because the engine was warmed up and my mechanic said everything is alright.

Drives good, idles bad.
I still need to change the oil on the car.
Won't start without MAF.
It seems to have AUDI/VW MAF.
AUDI fans.
Has a power steering leak.

Might have a boost leak, have to test for it yet.

The car is really hesitant to start when the engine is cold. I need to press the gas pedal to keep it running when starting until it idles by itself. After I see that it can hold idle, it idles at around 1.5k RPMs. I have to open the hood and adjust this: which I am not sure what this is, but my best guess it's IACV. When I adjust this valve after it has warmed up, it runs perfectly.


Here is a video of it:

Notice, after I revved it up, it started idling. It happens most of the time, so the engine might be getting flooded or something.

Few pics of it:



I am pretty sure that hole has to be plugged, but correct me if necessary.










Any help would be greatly appreciated.

Thank you.
