Over the past few days, I've noticed that my truck has been smoking more at idle than usual. Usually I can only see a slight haze from certain angles but lately its been more than usual. My question is how much smoke should I see when idling before I have a problem?

Stock injectors? If so you shouldn't see any. Bigger oversized and it depends on the company doing the work and the tuning. How many miles?

i think its caused by the fuel itself or the fuel pressure regulator, try running some diesel kleen, standyne, or 2 stroke see if it clears it up...
