CBP, the Kia mech seems to confirm what I said at the start of this thread, and that they knew all along this particular IAC for our model sporties was a not a good design and that's why it was further modified for later engines. Having said that it is still true that those in real cold climates probably still need it just to get started in the morning. An in/off switch would be useful there as it could be turned off once the engine was warmed. It shouldn't be too hard for someone with the knowledge to run a cutoff switch from that IAC connector wire into your dash area.....

Thinking about why you would bother with it at all since you and I are in a similar climate -but, yes, I guess it might be useful just for quicker ignition, if that's a factor. I think I will do it too if I am staying here another year. But I may be in Japan or Thailand and I'd have to sell the sport -it's all right hand drive there. I may just be on my motorcycle for awhile....

I DO have to crank it 2 or 3 times first, which I don't like. Not sure what the problem is -fuel? air?

99% of the stumbling is gone as Kia adjusted the mixture -she idles smoothly. It's just the morning startup......
