anyone having hesitation / sputtering problems with thier MDS (or their 2007's overall) systems?

mine was sputtering off the line (not floring it) as well as around 40-45mphat cruiseso i took her in to the shop. they "reset" the computer. Now my blue tooth doesnt work and it still sputters now at 45-50 mph cruise. it doesnt happen when i accelerate through those speeds but it does with or with out the cruise control on, and only around 45-50 mph...

Sound like you have an echo problem... but anyways...If your truck does not need all 8 cylinders it won't use them all.. if you take off lightly(as you described)the truck senses that and drops half the block.... at 40-45 same thing.... Tho if you hit a hilll i bet it changes.... it's the way the MDS is working.. it may suck... but it's trying to save you MPG's... even tho not much...
