$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: http://sphotos-b.xx.fbcdn.net/hphotos-ash3/156401_547385921941416_1503339905_n.jpg 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.

I cant tell if this is capped off or not, but yeah you overpaid.
Remove that boost controller, get the correct mafs, pull codes, boost leak test, check timing and search the forum. Wow, another Half broken 240sx for 2012!

Why on earth would you buy this? Your broke and you bought piece of shit that will require loads of money.
I could understand if you had money and don't mind spending couple of grand fixing it up. But your BROKE!!! You don't buy shit like this. Get rid of this shit and get yourself a none modified 240sx if that is what you want. And take it from there. Lately 240sx have been becoming way overpriced, even beat up trash that should be going to junkyard and smelted are being sold like they are gold. You might wanna try get into another RWD, for example Q45's are pretty cheap, g50's are selling around $1000 in great running condition. 300hp factory with none of that pop the hood bullshit idle this adjust that. Y33's are $2500, better looking in my opinion. Both have LSD factory and can easily drift without modifying a single thing.

In Vegas, people drift tax you a lot. You might be right, though.
