8 Most Common Causes of Ford F-150 Engine Hesitation During Acceleration

1. Dirty fuel injectors:

Fuel injectors are responsible for delivering the correct amount of fuel to the engine cylinders. When they become dirty, they can clog and restrict fuel flow, causing hesitation and other problems.

2. Faulty transmission: 

A faulty transmission can cause hesitation, especially when shifting gears. This is because the transmission is responsible for transferring power from the engine to the wheels. If the transmission is not working properly, it can cause the engine to hesitate as it tries to shift gears.

3. Low engine oil: 

Low engine oil can cause the engine to overheat, which can lead to hesitation and other problems. This is because the oil helps to lubricate and cool the engine components.

4. Faulty gear ratio: 

A faulty gear ratio can cause the engine to work harder than it needs to, which can lead to hesitation and loss of power. This is because the gear ratio determines how much torque is transferred from the engine to the wheels.

5. Cracks or rips in the engine: 

Cracks or rips in the engine can cause hesitation and other problems by allowing air to leak into the engine. This can disrupt the air-fuel mixture and cause the engine to run too lean or too rich.

6. Fuel pump: 

A weak or failing fuel pump can cause hesitation and other problems by restricting fuel flow to the engine. This is because the fuel pump is responsible for delivering fuel from the gas tank to the engine.

7. Coils developing shorted turns: 

Coils that are developing shorted turns can cause misfires, which can lead to hesitation and loss of power. This is because the coils are responsible for igniting the air-fuel mixture in the engine cylinders.

8. Tranny “hunting” for the right gear: 

A transmission that is “hunting” for the right gear can cause hesitation. This is because the transmission is constantly shifting gears in an attempt to find the right one for the current driving conditions.

Other causes of hesitation include: 

Slow electrical throttle response:

A slow electrical throttle response can cause hesitation. This is because the throttle controls the amount of air that enters the engine. If the throttle response is slow, it can cause the engine to hesitate as it tries to respond to the driver’s input.

Engine temperature sensor: 

A faulty engine temperature sensor can cause hesitation and other problems by sending incorrect information to the computer. This can cause the computer to adjust the air-fuel mixture incorrectly, leading to hesitation.

Mass Air Flow (MAF) sensor: 

A dirty or faulty MAF sensor can cause hesitation and other problems by sending incorrect information to the computer. This can cause the computer to adjust the air-fuel mixture incorrectly, leading to hesitation.

Dirty air filter: 

A dirty air filter can restrict airflow to the engine, causing hesitation and loss of power. This is because the air filter helps to remove dirt and debris from the air that enters the engine.

How to Fix Ford F150 Engine Hesitation During Acceleration

Engine hesitation can be a source of frustration for many Ford F150 owners. While it may seem like a minor inconvenience, consistent hesitation can lead to larger mechanical issues down the road. This guide is tailored to help you address and fix engine hesitation during acceleration in your Ford F150, ensuring a smooth and powerful ride.

1. Inspect and Replace the Air Filter

• Locate the Air Filter: Open the hood and find the air filter box.
• Unfasten the Box: Open the air filter box by releasing the clips and/or unscrewing any screws.
• Replace: Lift out the old air filter, insert the new one (ensure it’s oriented correctly), and re-secure the box.

2. Clean the Mass Airflow Sensor (MAF)

• Locate the MAF Sensor: Typically found between the air filter and throttle body.
• Remove the Sensor: Use a screwdriver to remove the screws and gently pull the sensor from the housing.
• Clean: Spray the sensor wire with an MAF cleaner. Allow it to air-dry thoroughly before reinstalling.

3. Examine the Spark Plugs and Wires

• Locate and Remove: Find the spark plugs, pull the plug wire, and use a spark plug socket to remove the plug.
• Inspect: Check the plug for wear or build-up and check the gap with a gapping tool.
• Install: Insert the new spark plug, hand-tighten it, and then use a torque wrench to tighten it to the specified torque. Replace the wire.

4. Clean the Throttle Body

• Locate: Find the throttle body by following the air intake system.
• Remove: Disconnect the air intake hose and remove any electrical connections.
• Clean: Spray throttle body cleaner onto a rag and clean inside the throttle body, scrubbing any stubborn deposits with a toothbrush.

5. Evaluate the Fuel Injectors

• Locate: Find the fuel injectors, usually mounted along the fuel rail.
• Remove: Detach the electrical connections and fuel lines, and unbolt the injectors from the rail.
• Clean: Utilize a fuel injector cleaner kit to flush the injectors, or soak them in cleaner and use a wire brush for any stubborn residues.
• Reinstall: Return the injectors to the rail, resecure all connections, and reattach the fuel lines.

6. Inspect the Fuel Filter

• Locate the Fuel Filter: Typically found along the fuel line under the vehicle or near the fuel tank.
• Remove: Use line wrenches to disconnect the fuel lines and remove the filter from its bracket.
• Install: Place the new filter in the bracket and reconnect the fuel lines, ensuring tight and secure connections.

7. Assess the Transmission

• Check Transmission Fluid: Ensure it is at the correct level and not burnt. Replace if necessary by draining old fluid and adding new fluid via the transmission dipstick tube.
• Inspect for Leaks: Check transmission seals and gaskets and apply a transmission stop-leak additive if minor leaks are detected.
• Manual Shifting Test: Manually shift through all gears during driving to detect any hesitation or slipping.

8. Scan for Trouble Codes

• Connect an OBD-II Scanner: Plug the scanner into the OBD-II port, usually located under the dashboard.
• Interpret Codes: Refer to the vehicle’s service manual or online resources to understand the codes.
• Address the Issue: Perform necessary fixes related to the trouble codes, which could range from replacing sensors to adjusting components.
