Thread: Idle's beautifully ... if I hold throttle to desired idle ... what's going on?

    Here is the Calibration file with the adjustments I made.
    (You have the "before" file in my post of the attachment before)

    1. It cranks right away.
    2. While cold, I have to hold the pedal down for it to stay in the idle area (about 800 to 875 RPM's).
    3. Once temperature is stabilized, it idles fine, in or out of gear. (It's like a threshold it reaches and it idles at zero TP, not as if it is really cold)
    4. Driving down the road, if I take my foot off the gas, around 30 MPH or so, it dips below idle point and I have to give it a little throttle.
    5. If I come to a stop at a light, as I ease off the pedal, it finds idle and holds.

    Looks like you may have to play with Throttle Follower and Throttle Cracker.
