P0602 Code on '03 3500 w/6 spd manual - Help!
I am a newbie here, and not quite sure if this should go in the engine/drivetrain forum, or here, so I'll try both I guess......
Recently took my rig into the local dealership with cold start issues. Long story, but they flashed the ECM, and replaced the injectors. Truck now seems to be running better, but is throwing a "P0602" code. They say that it is an error in the current software for the ECM.
Anyone out there have any knowledge on this?
Thanks
