My truck started jumping like a bucking bronco and at first i thought i got some bad gas but no it wasn't that simple. First i got some dry gas called heet and put that in the tank. No it didn't fix it. I changed the fuel filter and still didn't work. So i bought a carburator kit and changed the insides and gaskets. I then put it back together and put some new vacuum lines on thinking my problem was fix and still my truck is broke down and won't start!
