    Ok so i've noticed over the last week that my 08 GT has had low idle when started cold but i just thought it was because it was so warm here now this morning it was 40 outside and when i started the stang it ran rough @ about 800 rpm and then picked up to around 1500 rpm and ran smooth any ideas?

    Pull codes if you haven't already. If no codes, then clear the KAM and see what it does the next day.

    Ok checked for codes and there were none. What are you meaning by clear KAM?

    Disconnect the battery, pump the brake a few times, then let it sit for a few minutes. This will clear all the stored info in the ECU. When you start it in the morning, it will begin to "relearn".
