V4 STI idle issue

Morning everyone

I having some problems with idle at the moment, when its cold idles fine, once the car is warm the idle starts boucing between 600-800.

I have changed the idle control that came from a car that had no issue with idle at all, checked all the vaccum pipes,etc. Im running out of ideas to what i should be inspecting next, any help would be appreciated.

Car is running maf less, with ESL mapped by Duncan @ RaceDynamix 366hp.

Cheers

First port of call would be MAF, but there isn't one.

I'd have it back to Duncan.

Try adjust the idle control valve slightly.

I had the same issue with an Autronic , between that and a slight fueling change at idle sorted the problem
