    remove 25% from your throttle cracker table. so multiply by 0.75 to achieve this. if this helps then you know what table is causing issues.
    the cracker opens the iac with mph and rpm. sometimes the oem settings are too much and you get a push or cruise control sensation at low rpm.

    if 25% doesnt make any noticeable changes remove 50% from the stock table. (table * 0.5)
