Ka24de randomly dies when put in neutral

I’ve had my car sit for two years or so… but i did start it over a year ago and it was fine… anyways… i got it on the road but … it seems whenever i go clutch in or go neutral it just drops revs and dies. What’s up with that?

I’ll take it to my friend’s shop tomorrow to check it out but i wonder if i could try a few things myself.

Does it have a cold air intake?

Okay so it’s the idle control valve IAVC… anyone have any idea where i can get a good one and for how much?

try cleaning it first

Already did, no good.
