Vehicle is 2008 Dodge Ram 3500 4X4 pickup truck with 6.7L diesel engine. I was driving down hill on slippery road with foot off throttle, when applied gentle throttle pressure, the engine jerked violently several times, and causing the rear wheels to brake traction and the vehicle to fishtail. This event is intermittent, most often happens when driving with light throttle, then lifting off throttle to slow down, and when press throttle to accelerate, experience several rapid shudders or jerks from engine before the engine pull smoothly again. Vehicle has had this condition since new. This condition has been reported to two Dodge dealers, are unable to correct it, local dealer said he had same complaint from 6 or 7 other Dodge 6.7 L diesel owners.
