[QUOTE="Jeff C, post: 791658, member: 58631"] I had this problem a few years ago. I was still under warranty so I took it in with a copy of the TSB, the part was replaced, and the bucking stopped. DPFE = Differential Pressure Feedback EGR, which monitors the upstream and downstream pressures to calculate the EGR flow rate. Why wouldn't this cause a vehicle to buck if it was malfunctioning?
