Very helpful 03chevy.... Kudos

Welcome to the forum, and if I understand this right, it seems when the truck warms up, it stalls out right? If you keep the accelorator down, can you keep it running? I forget when dodge made the switch, is your motor EFI or carb? If it is a carb, I would think the problem lies in your choke. EFI and I bet the problem is with throttle position. Basically, it sounds like the motor is choking. When it is cold, the air/fuel mixture is a lot stronger then when it is warm. So I bet when it warms up, the proper adjustments are not being made. So to help out bud, let us know if it is EFI or Carb'ed.

HI

it is EFI, Willthe Idle control unit be at fault?

[junior3382]

That would be my guess. It is getting too much air when it don't need it and not nearly enough when it does. Typical of either a throttle control fault, or even mass air flow. Either way, there is a miscommunication. So yeah, I would start there.
