Ok I need some insight. I cracked the head of my 77 280z the summer before last. I was "given" a new head and added a lot of stuff while it was off. 3 into 2 header, no more smog crap, big bore tb, aftermarket fuel rail, zxt fuel pressure reg, zxt injectors, cranecams xr3000 ign and e core coil. thats just to name a few of the thing i have done. anyways the car runs great. its just the idle. let me be more specific. If i have the idle where it should be when the motor is wormed up(800-900rpm) it wont stay running when I start it up when it is cold. I have to give it a little bit of gas to keep it from stalling. On the other hand if i have the idle set up to where it runs at about 700rpm when it is cold once it worms up all the way it'll run at 12-13 hundred rpm. now that its winter time it has been a real pain in the butt. any outside thought would help.
thanks
