My truck runs great 90+% of the time. Sometimes i will slow down for something, or from a stop under normal acceleration, it will start BUCKing (Jerking) and i honestly can't tell for sure if it is a miss in the engine or something in the transmission, but it is violent. , if i let up, coast for a few seconds, then gently apply throttle until it gets back up to speed, it will then run fine. (Usually it only last for a short time, a few seconds to a minute)
For example i towed my 29ft fifth wheel 165 miles yesterday, i slowed for a railroad crossing from 59 mph down to about 5-10mph and when i applied throttle it started bucking, i had to lift the throttle, let it coast for a few seconds, then slowly apply throttle and it ran just fine. ran it for another 20 miles, no issues, slowing down to 40 mph a few times for some small towns, then slowed and turned onto a i75 ramp and had to enter the interstate at 50 because half the ramp was used up with a bucking, coasting, slow run up to speed. ran it for 30 miles at 70 mph no issues.
FWIW it makes no difference with or without the trailer, does the same thing both ways.
I am at about 900 ft above sea level
NO Codes have ever been thrown by this - Been at the dealer twice so far, an i am glad that it happened to the diesel tech
