One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine’s fuel injectors, and then pumps into the engine evenly.
Many Ford F-150 pickups with EcoBoost have a condition where the vehicle shudders or stalls during normal use. In the most severe of cases, the truck will actually go into “limp mode” causing the engine to lose all power.
What causes a misfire in a Ford F-150?
Ford F-150 Code P0303 Causes
Cylinder 3 misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it’s been a while since you had a tune-up.
Common reasons for this to happen: Clogged Fuel Filter: Over time and through normal use, your fuel filter will become dirty and clogged. When this happens, the flow of gasoline to your engine diminishes, which can cause hesitation and bucking.

Can transmission cause car to jerk?
Malfunctioning Transmission Control Module
The transmission control module controls the shifting as you accelerate, so you may experience delays with shifting, which can cause your car to jerk. While this is not as common of an issue as others in this list, it can certainly be the culprit behind your car jerking.
Does a dirty air filter cause your car to jerk?
A dirty air filter decreases the amount of air supplied to the engine. This can lead to an increase in unburned fuel that turns into soot residue. Soot can mound up on the spark plug tips making them unable to deliver a proper spark. In return, the car can jerk, idle, and in some circumstances, the engine can misfire.
