    Stalling in gear or at a stop: In the Holley EFI software (LINK), look at where this happens on the Base Fuel & Timing Tables. Determine if it's stalling
    due to a rich or lean condition. Also, the IAC Position is supposed to increase when you shift the transmission into gear (LINK). Sometimes the "neutral"
    area of the Base Fuel Table is fine, but the "in gear" area needs to be tuned. On the Base Fuel Table, the "in gear" idle area is just above the "neutral"
    idle area. Look at where the live cursor moves to, when you shift the transmission into gear. Is this "in gear" idle area, a little more rich (lbs/hr), than
    the "neutral" idle area? You'll have to look at the Learn Table too, since they function as one (LINK). Also, ensure the Target A/F Ratio Table and Base
    Timing Table are flat in these two idle areas. (Advanced Table For In-Gear Idle Control)
    May God's grace bless you in the Lord Jesus Christ.
