Hope someone can here. While accelerating at speeds at speeds above 40 or so, the truck jerks very hard 2 or 3 times. Sometimes you can feel a strange vibration right before it quits. Had tranny rebuilt last year. Took it back to the shop that did the work and they tell me its a mis tuned engine. Just recently I replaced the plugs, plug wires and coil pack. Any feedback would be appreciated!!
