Greetings all. With the cold weather I have more (blue) smoke than ever before. Why? Also, a real rough idle when at a stop light? Juice on 1/2.

Thanks,
Chuck

rough idle, excessive smoke. when was the last time your injectors were changed? check you oil and see if there is fuel in it. have your balance rates checked
diesels will smoke a little more when its cold out especially during warm up. idle may be rough due to it being cold out but if this is hapening after the truck is somewhat warm check your injectors.
