how to fix Honda Accord’s engine stalling during acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool down before working on it.

2. Inspect and Clean the Throttle Body

• Sub-steps:
  1. Remove the air intake duct connected to the throttle body (use a socket set).
  2. Disconnect the throttle position sensor connector.
  3. Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
  4. Reinstall the throttle position sensor and air intake duct, ensuring a secure fit.

3. Check and Replace Spark Plugs

• Sub-steps:
  1. Remove the ignition coil cover (if applicable) using a socket set.
  2. Disconnect ignition coil connectors and remove the coils.
  3. Remove spark plugs using a spark plug socket.
  4. Inspect the spark plugs for wear or carbon buildup; replace if necessary.
  5. Reinstall new spark plugs and ignition coils, torque to manufacturer specifications.

4. Fuel System Inspection

• Sub-steps:
  1. Locate the fuel pressure test port on the fuel rail.
  2. Connect a fuel pressure gauge to the port and turn the ignition on (do not start the engine) to check pressure.
  3. If pressure is low, inspect the fuel pump and filter for blockages; replace as necessary.
  4. Reassemble the fuel system components securely.

5. Clean or Replace Mass Airflow Sensor

• Sub-steps:
  1. Disconnect the MAF sensor connector.
  2. Remove the MAF sensor from the air intake duct.
  3. Use MAF cleaner to gently clean the sensor wires; avoid touching them.
  4. Reinstall the MAF sensor and connector securely.
