ok so the car cranks starts but idles low and dies.but if i give it a couple of good revs it stays idling low and then warms up and idles good.this only happen when the car has beenn sitting for a couple hours.i know it could be my injectors or fuel pump or could it be something else.its a jdm b16 motor.

 

fast idle control valve? i think thats what its called. when the car is cooler it idles higher so that the engine will stay running, once it hits operating temp it goes back down to normal idle.

that may be it but im not even 25% sure, so bump for you

 

thanks im goin to try another one see what happens
