Faulty Fuel Pump
The fuel pump moves fuel from the tank to the engine. A failing pump cannot supply enough fuel. Low fuel pressure makes the engine struggle under load. This results in jerking or stalling. A noisy or weak fuel pump signals trouble. Testing and replacing the pump restores smooth power delivery.
Ignition System Problems
The ignition system plays a big role in your Ford F150’s performance. Problems here often cause jerking during acceleration. The system creates sparks that ignite the fuel-air mix in the engine. If sparks are weak or inconsistent, the engine stutters or jerks. Two common ignition parts cause these issues: spark plugs and ignition coils.
Worn Spark Plugs
Spark plugs wear out over time. They create the spark that starts combustion. Worn plugs produce weak sparks. This makes the engine misfire and jerk. Dirty or old plugs cause poor fuel burning. This leads to rough acceleration and lower power. Replacing spark plugs regularly keeps the engine smooth.
Damaged Ignition Coils
Ignition coils turn the battery’s voltage into a strong spark. Damaged coils cause weak or no spark at all. This leads to engine misfires and jerking. Faulty coils often cause rough idle and poor fuel efficiency. Replacing bad coils restores proper spark and smooth driving.

Air Intake Blockages
Air intake blockages can cause your Ford F150 to jerk during acceleration. The engine needs a steady flow of air to work well. When air flow is blocked, the engine struggles to get enough oxygen. This makes the truck feel rough or jerky as you press the gas pedal.
Dust, dirt, and debris can clog the air filter. This reduces the amount of air reaching the engine. A dirty air filter is a common cause of jerking. It also lowers fuel efficiency and power.
Sometimes, animals build nests inside the air intake system. These nests block air flow and cause engine problems. Leaves and small branches can also get stuck in the air intake.
Checking the air intake system is a simple step to fix jerking. Cleaning or replacing the air filter often improves performance. Keeping the air intake clear helps your F150 run smoothly.
Symptoms Of Air Intake Blockages
Your truck may jerk or hesitate when accelerating. You might hear unusual noises from the engine area. Fuel consumption can increase unexpectedly. The engine may run rough or stall at low speeds.

Open the hood and locate the air filter box. Remove the air filter and check for dirt or damage. Look inside the air intake tube for debris or nests. Use a flashlight to see clearly inside tight spaces.
Cleaning And Replacing Air Filters
Tap the air filter gently to remove loose dirt. Use compressed air to blow out stuck dust if available. Replace the air filter if it looks very dirty or torn. Follow the owner’s manual for the right filter type.
Preventing Future Blockages
Check the air filter every few months or after driving in dusty areas. Keep the engine bay clean and free of leaves or debris. Park your truck in a garage or covered area if possible. Regular maintenance keeps air flowing freely.
Exhaust System Concerns
The exhaust system plays a key role in your Ford F150’s performance. Problems here can cause the truck to jerk during acceleration. Bad airflow or blockages in the exhaust can create engine strain. This strain can lead to jerking or hesitation when pressing the gas pedal. Checking exhaust system issues helps keep your truck running smooth.
Clogged Catalytic Converter
The catalytic converter cleans harmful gases from the engine. Over time, it can get clogged with carbon deposits. This blockage reduces exhaust flow and causes back pressure. Your Ford F150 may jerk or lose power while accelerating due to this pressure buildup. A clogged catalytic converter often causes poor fuel economy and engine misfires. Replacing or cleaning the converter can restore normal performance.
