    Random coming to light stall

    Ls2 6.0, 411 pcm, Random stall occurs when going from any gear into neutral. The rpms fall normally down to idle a majority of the time. Every once in a while rpm will fall below desired idle, hunt for one second and then idle perfect no big deal. In my log you can see twice it falls below idle, stumbles down to 200-150rpm then stalls. On the times it finds idle my STIT comes on quick and jump up to 4.0g/s sometimes. On the times it stalls its like STIT doesnt kick in fast enough and sometimes even goes negative. Hopefully I attached files correctly

    We need a little more info on the datalog.
    We need the IAC position at idle.
    Also need to add the MAF airflow g/s at idle.

    It likely needs a little more minimum airflow added in gear, but it's hard to say how much without all of the info.
