Why is my truck sputtering when I accelerate?

One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. Since the fuel filter, pump, and injectors work together as part of one interconnected system, dirt and debris need only clog one part to cause the others to fail.

Why is my Ford F150 stalling at idle?
