03 Duramax Injector Replacement
Thanks for the replys. The warranty is out. July 02 Manufacture date.
Starts fine in cold weather (down to -10F) without the block heater. Would bad injectors cause hard starting? Have never had to add oil between changes.
Got some bad fuel about a month ago then started smoking excessively at idle. Changed fuel filter and added BG 244. Still smokes at idle.

sorry to jump into the conversation, but i have the same problem and was hoping for explinations. grey smoke at idle, but only once and a while, goes away while driving. its an 04 duramax with 122,000 miles. does the recall affect me? how would i go about checking the balance rates of the injectors? if there aftermarket injectors, could it be just putting too much fuel in at idle, but burning it off normall at road speeds? new to the duramax community, just trying to get a better understanding. thanks!

Thats what the symptomes usually are for injectors smoking at idle only. goes away as the rpms go up ..it only gets worse with time . make sure your dipstick level isnt over full and doesnt smell like diesel..usually the dealer wont fix it for just smoking the balance rates have to be way out of spec or the truck has to be making oil..the only way i know how to have the balance rates checked is to take it to the dealer might cost you a bit ..i know some programmers can do it not sure which ones..
