So after a trouble free initial trip around block yesterday, today the gremlins showed up. Remember I have the new Fi-Tech EFI. Well today I crank the truck and it will not idle below 1,600 RPM. No one has touched it between yesterday and this morning. After trying to fix it by going back to base tune no luck. The idle speed is still set at the same 650 according to the ECU. Called Fi-Tech support and they told me to set the IAC Steps to a value between 3 and 10. I will try that ASAP and report back.
