why does my Honda Civic 10th Generation (2016-2021) engine stall when I accelerate

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuel System Inspection

• Tools Required: Fuel pressure gauge, socket set.
• Sub-steps:
  1. Locate the fuel rail and connect the fuel pressure gauge.
  2. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure; it should be within manufacturer specifications (typically 40-50 psi).
  3. If pressure is low, check the fuel pump and fuel filter for blockages or failure.
  4. Replace the fuel filter if clogged, and consider replacing the fuel pump if it is not functioning properly.

3. Air Intake System Cleaning

• Tools Required: Cleaning supplies for MAF sensor, socket set.
• Sub-steps:
  1. Remove the air intake duct to access the MAF sensor.
  2. Carefully clean the MAF sensor with MAF cleaner. Do not touch the sensor wire.
  3. Inspect and replace the air filter if dirty.
  4. Reassemble the air intake duct securely.

4. Ignition System Replacement

• Tools Required: Socket set, torque wrench.
• Sub-steps:
  1. Remove the ignition coils by unscrewing them from the engine.
  2. Inspect the spark plugs for wear (replace if necessary) and ensure proper gap settings.
  3. Replace any faulty ignition coils with new ones.
  4. Torque the screws to the manufacturer’s specifications.

5. Throttle Position Sensor Testing

• Tools Required: Multimeter.
• Sub-steps:
  1. Unplug the TPS connector.
  2. Using a multimeter, check the voltage while manually moving the throttle plate.
  3. If the readings are inconsistent or out of spec, replace the TPS.
