Idle issue when coming to a stop?

[sileighty83]

:sadwavey:So basically after driving it for a while now I've narrowed it down to this.

-Motor:KA24DE

-Problem:Idle drops down to zero rpm when I press the clutch in and brake to a complete stop...drops then in 1 second goes back up to regular idle.

I was thinking maybe my iacv valve is stuck or needs cleaning, but not 100% sure. any help is appreciated!

thanks all

I have this, I dont think its your IACV, I think its your PCV valve.

I cleaned my IACV and still got it. I got a higherflowing PCV valve and it stoped.

Also this will happen sometimes if your using the AUTO ecu with a 5speed swap.
