I have put a total of 5k miles on the truck. I was towing my boat home from the Colorado river and the truck starts blowing a ton of black smoke.

I am convinced now that the injection system in the duramax is a failure and in need of a recall. Time to start writing letters and making phone calls. My faith is lost in my Duramax. I will always be waiting for the black smoke to start blowing.

Sorry to hear you had a bad expereince. Hope everything works out for you in the end :)

You might have blown an intercooler tube. Or clogged airfilter.

Injectors will normally cause rough idle, rattling, and some white smoke at idle sometimes.

Check balance rates with a Predator or Tech II.

How do you only put 5000 miles in 2+ years? Sorry to hear about your problems and hop GF was OK.

I bought the GMPP 3 year/36k mile warranty, when my truck had 42k miles for $1250.00 from the dealer.:ro)

42 K plus 5 K = 47 K, right?

Use your CMPP warranty, right?
