also looking around at egr symptoms it shows that rough idle is a symptom, which i do not have, idle on the truck sounds normal. the stutter only happens every once in a while off the line and whenever under a load (uphill, push gas pedal etc) the stutter off the line doesn't happen everytime, i'd say around 80% of the time. also every once in a while i can get it to run as if nothing's wrong and then the next tap of the gas pedal to pass someone it won't accelerate.
