why does my Ford F-150 14th Generation (2021-2024) feel like it’s stalling when driving

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface with the engine turned off and cool.
• Disconnect the battery to ensure safety while working on electrical components.

2. Check Fuel Pressure

• Tools Required: Fuel pressure gauge, safety goggles, gloves.
• Locate the fuel rail and connect the fuel pressure gauge.
• Turn the ignition to the "ON" position without starting the engine to check the fuel pressure reading.
• Compare the reading against the specifications in the service manual (typically 50-60 psi for F-150).
• If pressure is low, check the fuel pump and fuel filter for blockages or failures.

3. Inspect and Clean Throttle Body

• Tools Required: Socket set, throttle body cleaner, rags.
• Remove the air intake duct leading to the throttle body using the socket set.
• Disconnect the throttle position sensor connector.
• Remove the throttle body from the intake manifold.
• Clean the throttle plate and body with throttle body cleaner and a rag.
• Reinstall the throttle body and reconnect the sensor connector.

4. Check and Replace Spark Plugs

• Tools Required: Socket set, spark plug socket, torque wrench.
• Remove the ignition coils by unscrewing them carefully.
• Extract the spark plugs using the spark plug socket.
• Inspect the old plugs for wear or fouling and replace them with OEM or equivalent plugs.
• Reinstall coils and torque them to manufacturer specifications (usually around 10-15 ft-lbs).

5. Clean or Replace Mass Airflow Sensor

• Tools Required: Torx screwdriver, MAF cleaner.
• Disconnect the MAF sensor electrical connector.
• Remove the MAF sensor from the air intake duct using the Torx screwdriver.
• Clean the sensor wires gently with MAF cleaner or replace it if damaged.
• Reinstall the MAF sensor and reconnect the electrical connector.
