300zx Starting Problem. PLEASE HELP!

[ONEbadZ32]

My car turns on fine when completely cold but if i shut it off, or if i stall it by accident, i struggle to turn it on. I have to crank, crank, and crank until it turns on. But when the car is completely warmed up, it turns on just fine. What could be the problem? Help please!

Idle air control valve.

When ever our cars are cold the idle air control valve is working hard to get everything up to its normal temperature. Its constantly adjusting things so that it doesn't stall.

Things you could do:
First check the plugs on the valve make sure there is no green crud on them.
Next would be take the valve off give it a good cleaning. If that doesn't help let us know.

No distributors on the VG.

Ima check the idle air control valve because my idle does bounce when im on gear and then i put it on neutral as well. I just havent had time to mess woth it. But i will soon. Do u know if the idle air control valve is the same on a NA plenum and a TT plenum?
