why does my BMW X5 G05 (2019-2024) feel like it’s stalling when accelerating

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery before working on electrical components.

2. Inspect and Replace Spark Plugs

• Sub-steps:
  1. Remove the engine cover if applicable.
  2. Disconnect spark plug wire or ignition coil from the spark plug.
  3. Use a spark plug socket to remove the old spark plugs.
  4. Inspect the old spark plugs for signs of wear or carbon fouling.
  5. Install new spark plugs, ensuring they are gapped correctly (refer to the specifications).
  6. Reattach the spark plug wire or ignition coil.

3. Clean or Replace Throttle Body

• Sub-steps:
  1. Remove the air intake duct to access the throttle body.
  2. Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
  3. If the throttle body is damaged, replace it with a new component.
  4. Reinstall the air intake duct securely.

4. Test Fuel Pressure

• Sub-steps:
  1. Locate the fuel pressure test port on the fuel rail.
  2. Connect a fuel pressure gauge to the port.
  3. Turn the ignition to the "on" position without starting the engine to check for pressure reading.
  4. If the pressure is below specifications, inspect the fuel pump and replace if necessary.

5. Check Mass Airflow (MAF) Sensor

• Sub-steps:
  1. Locate the MAF sensor in the air intake system.
  2. Disconnect the electrical connector from the sensor.
  3. Remove the MAF sensor from its housing.
  4. Inspect for dirt or debris; clean with MAF sensor cleaner if needed.
  5. Reinstall the MAF sensor and reconnect the electrical connector.
