Hey guys I need some major help....
I have spent a grip load in turbo mods..... I just recently got the block rebuilt, got the fuel mods done.... My problems...
My car doesnt idle it wants to die when I put it in nuetral and try and stop, I have to give it gas so it wont die and thats dangerous sometimes.
My car runs pig rich at idle and spews smoke.... I have the vortech sfmu and have adusted the hell out of it with all the srings and disks... and I have the stock injectors.
At wot I get fuel cut... I have the missing link.... still doesnt help

this all sux cause i have a built motor and am only running 5 psi... if you guys have any suggestions on my problems help a bro out...
I am honestly thinking of jes selling the dam thing.

The 4G64 has a MAS right? If so, its more than likely reading too much airflow and is causing fuel cut and causing the computer to dump too much fuel. Also, if the car has a MAS, does your BOV have a dump tube going behind the MAS? That could cause it to die at idle possibly. Just a few ideas, lemme know if I'm wrong :)

no dood i have the 420a sorry i didnt mention it.... any other advise?

Whoops. I was guessing 3G cause of the Y2K thing, anyhow. Have you changed your o2 sensor and fuel filter lately? If not, I'd recommend doing that, ya never know. With the fuel cut you're getting, it sounds like a electronic problem. It'd be a good idea to check the TPS sensor, etc. I'm sure Dino could give you some advice :)
