I let my truck run totally out of gas. Filled it up then it kept dying. Have added spark plugs/wires, carb kit, fuel filter, fuel pump, charcoal cannister. But when I have to stop the truck and then push the gas, it wants to die. I'm at a loss here, IDK what to do anymore......As long as I have the gas pushed down it runs, but let off the gas and it wants to die.....
