Symptoms
  • Engine stalls at idle or when coming to a stop
  • Check engine light illuminated
  • Rough idle prior to stalling
  • Unresponsive accelerator pedal after stopping
  • Erratic engine behavior (e.g., fluctuating RPMs)
Diagnostic Steps
  1. Scan for error codes using an OBD-II scanner to identify potential faults.
  2. Check engine oil level and condition; low or dirty oil can affect engine performance.
  3. Inspect the throttle body for carbon buildup or malfunctions.
  4. Test the fuel pressure to ensure proper fuel delivery to the engine.
  5. Inspect the mass airflow sensor (MAF) for cleanliness and proper operation.
  6. Check for vacuum leaks in hoses and intake manifold.
Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, cleaning supplies.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool down before starting repairs.
2. Clean or Replace the Throttle Body
  1. Remove the air intake duct by loosening the clamps and disconnecting any sensors.
  2. Unbolt the throttle body from the intake manifold using the socket set.
  3. Inspect the throttle body for carbon deposits; clean using throttle body cleaner and a soft cloth.
  4. If severely damaged, replace the throttle body with a new one.
  5. Reinstall the throttle body and tighten bolts to the manufacturer's torque specifications.
  6. Reconnect the air intake duct.
3. Inspect and Clean the Mass Airflow Sensor
  1. Locate the MAF sensor along the intake path.
  2. Remove the MAF sensor from the housing using the socket set.
  3. Clean the sensor with MAF cleaner spray; do not touch the sensor element directly.
  4. Reinstall the sensor securely.
4. Check and Repair Fuel System
  1. Connect the fuel pressure gauge to the fuel rail.
  2. Turn the ignition to the "on" position without starting the engine and check the pressure reading.
  3. If pressure is low, inspect the fuel pump and filter; replace if necessary.
  4. Reconnect all lines and ensure no leaks are present.
