last friday, truck all of a sudden had a rough idle and no power, and surges under throttle. pulled all coil packs tested, looked over everything else, all looked fine, saturday problem was still there but not quite as bad, sunday and monday it sat was going to make an appointment at the dealer for tuesday, tuesday it sat and i drove the wifes car, went for a little test ride after work and all was fine, put chip back in and all was fine, W.T.F.....i guess it just wanted the holiday off to. im gonna cancle the app. at the dealer, they wont find anything this way. anyone know of a reason for this and or a way to prevent this from happening again...



thanks jim
