Motor question
Guys, need a little help before I take my truck to the shop. I have an 05 GMC 2500HD D max with the edge attitude and the problem Im having is every now and then ( happining more often then before) going down the road Ill look in the rear view mirror and see tons of smoke comming from the tail pipe, black and gray. EGTs go through the roof and Im not getting any power. It actually slows down and just smokes. What is going on???????
