I have a 99 Expedition and I have replaced wires, plugs, and flushed the injectors. I have a back fire between 45 and 50 MPH. The truck feels like it is starving for gas. It seems to now start it at 60 also. When I step on the gas hard it spudders hard then seems to get gas. HELP !!!!!

Yea, had a Buick that did something like that. It ran fine but when you got on the freeway the car would start bucking/ spuddering. What happens if you drive it in 2nd gear?

More than likely you have a coil on plug going out. Is the check engine light coming on.
