Why does my truck jerk at 50 mph?
Hi There, The jerking reaction you are describing may indicate a dirty or failing mass air flow sensor which is a unit that monitors air intake and relays this info to the ECM which then makes adjustments to the fuel supply. This could also possibly be related to intermittent fuel pressure or an ignition problem.
Why does my truck keep sputtering?
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 does my truck jerk at 40 mph?
