My friends 4.9 was cutting out, bucking under part throttle, especially in town. I unplugged EGR line and it runs PERFECT now. The mileage is much better too, it was about 10MPG before, its at least 15 now.

As for my own truck, I got it running today, it doesn't buck anymore but almost feels like it has a constant miss (just a slight one) I might replace the plug wires and see if it helps since I bumped one the other day when it was running and got shocked.

I'm going to make a restrictor for myself and one for my friend out of aluminum after I go back to school next week.
