Like the title says.. after some mods.. I start up the car it runs fine.. I pull out on the road.. everything is great but I come to a stop and it dies.. start back up.. idles great.. So I was thinking.. idle air control? Is there a way to test it? and if it is.. where can I buy one? I have looked all over the net and can't find any place selling.. Thanks in advance..

AFM (airflow meter) almost certainly.Clean it with electric contact cleaner or buy a new one. Z32 AFM's work fine in it.

Next check aac valve, clean if nicessary (see skylinesaustralia for help)

Next check TPS.
