1982 supra runs really rough when cold
 

Hi my name is tyler and I am new to this forum. I just bought a 1982 supra. The car runs great except when it is cold. In the morning or if it sits for mor than a couple hours, i go to start it it and it runs very rough. I take off and it goes then slows down and almost dies then takes off again. It keeps doing this for the first half of a mile or untill its warmed up a little. Was wondering if anyone had any ideas or suggestions. Thanks alot for your guys help.
