280ZX Stalling Problem-HELP!

[Datsun Parts]

I have a 81 Turbo and and runs perfect! Problem is it stalls after a few seconds when you stop (for a light or in traffic), in neutral or park it idles great, but as soon as you put it in drive it slowly dies like its starving for fuel? I have checked for vac. leaks, recently tuned the car with new injectors, FPR, cap , rotor, wires, plugs and so on. Even rebuilt the turbo. I was told it could be a idle control valve and that the idle is not adjustable? Anyone else have ideas? Here is a few photos of her. Thanks in advance, Al

Have you checked the brake booster for leaking diaphragm causing a vac leak?

the idle control valve as their calling it is the air idle control valve or the air regulator, it ups the RPM's when you start it cold like a choke.

 

try just unplugging it and see if it still does that.

 

 

 

theres also the FSM available for DL at Xenon Z car

The IAC is "dumb" and slowly closes a gate valve to bring down the idle RPM's after a certain time. If this was the problem, you'd see different behavior when the engine is cold or warmed-up.

 

The Airflow meter probably needs adjustment since the idle is kicked up on an A/T when you're in gear. I would think you'd need to richen it a bit so it won't starve for fuel and die. Something to try if upping the idle with the linkage stop screw on the throttle body doesn't work.
