So the story continues....I have noticed that the truck as been running a little sluggish lately and then last night on my drive out of town I was forced to slow down considerably and when I went to get back onto it the truck had no get up and go and the pedal was on the floor. I looked back in the rear view mirror and all I saw was white smoke pouring out of the exhaust. I then backed off of it and it was fine. I called the dealership today and naturally they want to see it and their initial explanation is either oil or blown injector. Any other thoughts? It has close to 60,000 on it.....
