Why car skips when I accelerate at slow speed?
More often than not, when a car jerks when accelerating at low speeds, it’s because there’s a problem with the spark plugs in it. A simple tune-up should be able to stop the jerking once and for all. But there could also be a problem with the air intake system or with the catalytic converter.
What causes an engine to hesitate on acceleration?
A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.

When does your car hesitate at 45 mph?
I started getting a hesitation/bucking in my 2001 F150 SCREW 5.4L 96,000 miles. It does it most often when you are barely on the gas at 45 to 50 MPH and then you press the gas to accelerate. It hesitates for a second and then takes off.
Why does my Mitsubishi Starion have engine hesitation?
As another example, I still have a 1987 Mitsubishi Starion, which ran perfectly for 35,000 miles. Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again.
Why does my car hesitate when I open the throttle?
Engine Hesitates, Stumbles, Lacks Normal Power. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture, and when extra fuel is needed if the throttle suddenly opens wide.
