Hi! I'm new here but have poked around in the forums for quite awhile. My 2003 LB7 has light grayish-white smoke at idle and a puff of the same color when I start from a stop. It seems to be worse if the truck idles longer or if I decelerate slowly from cruising speed to a stop without much use of the brakes. The fuel filter is new, the air Cleaner is not restricted, and I recently cleaned the MAF sensor. I usually run a fuel additive (amsoil).The truck has 104,000 miles on it but I've only had it for the last 27K so I'm not sure of it's injector history. Reading other posts it sounds as if my injectors might be going bad? If so is the condition that usually causes this color smoke covered by the 200K injector warranty or not? My apologies if this is a rehash of existing posts. I do have a Banks Stinger system that I run on the economy setting if it makes any difference.
Thanks
