what steps to take if my Ford F-150 13th Generation (2015-2020) keeps dying at stoplights

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to ensure safety.

2. Inspect Fuel System

• Tools Required: Fuel pressure gauge, basic hand tools.
• Steps:
  1. Locate the fuel rail on the engine.
  2. Connect the fuel pressure gauge to the fuel rail's test port.
  3. Turn the ignition to the "On" position (do not start the engine) and check the fuel pressure reading against the manufacturer's specifications.
  4. If pressure is low, check for fuel leaks and inspect the fuel pump and filter for faults.

3. Clean Throttle Body

• Tools Required: Throttle body cleaner, screwdriver, clean cloth.
• Steps:
  1. Remove the air intake duct to access the throttle body.
  2. Spray throttle body cleaner into the throttle body while opening the throttle plate.
  3. Wipe away carbon buildup with a clean cloth.
  4. Reinstall the air intake duct securely.

4. Test and Clean IAC Valve

• Tools Required: Basic hand tools, cleaning solvent.
• Steps:
  1. Locate the IAC valve (typically near the throttle body).
  2. Remove the IAC valve from its mounting.
  3. Clean the valve using a suitable solvent to remove carbon deposits.
  4. Reinstall the IAC valve and ensure it's properly secured.

5. Inspect and Replace MAF Sensor (if necessary)

• Tools Required: Basic hand tools, MAF sensor cleaner.
• Steps:
  1. Disconnect the MAF sensor connector.
  2. Remove the MAF sensor from the air intake tube.
  3. Clean the sensor's wire with MAF sensor cleaner (do not touch the sensor wire).
  4. Reinstall the MAF sensor and reconnect the connector.
