    Need help on how to control cold idle speed on 8 stack system without using an IAC valve. Engine starts, idles perfectly when warm but will stall when cold unless I keep the throttle open to keep it running until temperature reaches about 140F.
    Any help would be greatly appreciated!
    Thanks

    You just need a better cold tune and some timing work. I can remote connect and tune this for you.
