ive only had this truck for a month now first powerstroke. Early 99 auto 185k with superchips tuner. When you come to a stop about 99 percent of the time it acts like it is running on 7 cylinders you can tap the gas to ramp up the rpms a little and it may clear up not always. When you drive it though it runs flawless. The only thing that has been done different in the last few days is i changed the oil 2 quarts lucas the rest rotella 15w-40 and i did notice after about 100 miles of driving when you shut it off and went to restart it now starts instantly. But it is very hard on a cold start start and then die? its been about 20' in the am up to about 35 or so during the day. could the oil be to thick and causing the miss and you can drive it for an hour and it still does it. I don't think that it done this when i bought the truck but not 100% sure
