Default RE: how to adjust idle

its common for the idle to hang like that from factory, what does it normally idle at 1300? If i am understanding correctly there is a hanging idle mod I did it when I first got my car and allows rpms to drop a lot faster, havent had any probs https://mustangforums.com/m_425306/tm.htm You can also adjust it with handheld tuner and/or check your throttle cable
