here is my problem with the car it is idling very weird and shuts off.

This just started today when the car fully warmed up it will sometimes idle at 400-500 rpm and then it will stay there for couple seconds it will just cut off. But some times it idles just fine at like usual 800-900 rpm.

My set up in my sig. the car is fully tuned.

Thanks in Advance

 

clean your iacv

 

any idea on how to do that or where can i get it done

 

It should be on your Intake manifold...just pull it off and clean it with some car cleaner..but the location of it varies on specific engines. goodluck
