my car stalling

[s13silvia03]

well here it goes, when im driving at fast speeds and then put the clutch in to slow down my car will stall, it also stalls if i have my a/c on when i start the car, and last night i was at red light just sitting there and it like started to stall but then kicked back on all the way, does anybody know what this could be or has anyone ever had this happen to them? Any help would be greatly appreciated

Could be dozens of things but most common cause of stalling at idle is the aac/iacv valve (called different names but it does the same thing). It's that valve on the back of your intake manifold way underneath with the vacume hose and the wires coming out of it. By the way, I'm referring to the KA24DE, never really saw a KA24e before.
